When I try Signing in, YM suddenly closes. I've tried reinstalling with the same version, tried reinstalling with older versions. Even tried installing Yahoo! Messenger Beta 9. yet it still doesn't work and I've also looked through Yahoo Q&A. can any of you guys help me?

hmmm. Have you try to uninstall, restart your computer, and then install it again?

Probably you want to try to login with another account, and see what happen

XP or Vista? Or any other OS.

Nope.. Tried that.. still doesn't work.



XP.

By the way, yahoo messenger has known issue with Windowsblind.

Probably there are other softwares in your computer that conflicts with yahoo messenger.

Until I figure this one out. I'm assuming that the problem is with Yahoo's end.

I had the same problem a short while back. I ended up uninstalling and reinstalling several times before it stopped.

I had the same prob couple months ago. I cleaned up my registry with RegClean and that solved the problem for me

I need to buy the program to repair it.

Or probably you don't if you can do it manually

(Do it after you uninstall the yahoo)
Go to start -> run -> type "regedit" -> enter

and then press ctrl + F and search all entries for "yahoo" and delete them. It will take some time though, those registries are everywhere in your computer

Restart and re install...

Thanks on the process of trying your idea.
and btw.. found this DLL Hell. it may be the problem here on my case.
DLL HELL

EDTI: Did your the exact procedure you told me.. it still doesn't work. xD

Go to www.bootdisk.com Click UTILITIES on the right hand side, scroll down to registry cleaners, download EASY CLEAN V.2. (its completely free)

Go to your control panel and un-install Yahoo from there... Open and install Easy Clean V.2 and run it. When it opens click the "Unecessary" Tab and then click FIND. this will find all keys and values in your registry that are no longer being used. Thus, it will take out Yahoo Crap

thanks.. there was a program on the startup menu called kxvo that prevented me on using the YM. and thus fixed the problem..

If you still have kxvo.exe you need to read this: techguy.org

EDIT: Malware....ran into it before.
