Yahoo has begun blocking Cerulean Studios' Trillian software from communicating with its own instant messaging software as part of its plan to limit third parties from piggybacking on its service.

On Thursday, some Trillian users began reporting an inability to communicate with their Yahoo Messenger contacts. A Yahoo spokeswoman on Friday morning confirmed that Trillian users' inability to access Yahoo Messenger was the result of recent policies put in place by the Web giant.

Yahoo last week announced that it would require people who use older versions of Yahoo Messenger to upgrade to more recent versions. Coinciding with the upgrade, Yahoo said it would likely disable access to outside IM services such as Trillian. Yahoo set a deadline of Wednesday for its forced upgrade and its intention to disconnect Trillian.

"If this has affected the way in which third parties interact with our service, it is merely a byproduct of our efforts to implement preventative measures to protect our users from potential spammers," Yahoo spokeswoman Mary Osako said.

A notice posted on Trillian's Web site informed users about "an issue that may cause a crash or invalid password when trying to autoconnect to Yahoo," the site read. Trillian users who reported the problem said they were unable to view their buddy lists when connecting to Yahoo.

"We are aware of the current connectivity issues with Trillian and the Yahoo network, brought on as a result of Yahoo's recent protocol upgrade," Scott Werndorfer, co-founder of Cerulean, said in an e-mail statement. "We are working hard on a solution and will update our Web site when more information becomes available."

A day after last week's Yahoo announcement, Trillian released software patches that were aimed at allowing it to continue accessing Yahoo and MSN buddy lists. But as of this week, those patches do not appear to be working.

Update:
Yahoo! Patch Beta 1 is available for Pro customers; patches for 1.0 and .74 are on the way and will be released once the patch is 100%. Members can get their copy by logging in to Trillian's Members Area . (Thanks Pointer)

Yeap and the patch works great.

PS: All over the net now.

I don't see what the big deal is. If anyone exclusively uses Yahoo! Messenger they don't deserve to be talked to anyways.

if they exclusively used it, they wouldn't be using trillian, now would they?

Someone want to explain why Yahoo and AOL don't take any legal action against Cerulean Studios, for unauthorized acess to their chat networks? It'd be an easy win.

bad press and it wont get them anyway.

even if cerulean studios loses the lawsuit, there will be others who make new clients to connect to their networks.

i think they awnt just one client on their network they can control, imagine if they did get CS banned, it'll create thousands of more clients that they'll wont be able to control and it might hurt them in the end more than Trillian can.

remember the napster? once it got banned, what happened after? Kazza, Grokster, Morphues, and many others.

same thing will happen here.

??

the napster was the leet

the napster gave me a std.

It doesn't just affect Trillian... GAIM under linux won't connect. It truly sucks because I can no longer chat with my brother while using linux. BAh.

mirainda i heard was having problems too. basically all third party clients have problems

There is a patch available at the trillian website for 2.0 and it works just fine for me right now. (It's a beta 1 patch). Anyway, I'm up and on Yahoo again. This story had barely broken on ieX and Cerulean had a patch out. (although the problem has been there for about two days).

Ummm... Linux users I use AOL's AIM on Linux it may not be what you like to use but it work AOL does provide a Linux version of there AIM software. AIM for Linux.... but back to the main topic i must say AOL Y! and MS are pissin me off cause i bought the full pro version of Trillian and now i can't use it... you know how mad that makes me at them not CS its not there fault. BLAH opening trillian right now.. "surfing the web for patches*

I still can connect to ICQ now...but i'm not sure if that is the same thing....

*sighs*

Did this not happen in the past, too?
They'll change code and everything will work again, or is it something different now?

Yourself? Or your dorky friend who you need the Yahoo support for in Trillian to begin with? Yeah some "friend."
