Issue with yahoo messenger

It all started with trying to click on yahoo messenger and the process shows for a few seconds before crashing.
On the taskmanager, everytime I bring up yahoo messenger, the sysfader.exe gets fired up and then ypager.exe, which eventually disappears along with sysfader.exe

I have disabled sysfader by unchecking the "User the following transition effects for tools and menus" on Desktop properties -> appearance -> effects.

My yahoo messenger is still crashing thought now I don't see sysfader firing up.

I found a debugger and traced the stack uwind for the crashing process.

Any idea what eueoeqi.dll is all about? Looks more likely to be a yahoo app. Any idea how I can report this to them?

Thanks in advance,
