Re: messenger not signing in

There is a virus. Try installing an antivirus.. or try this, run Command Prompt, Start>Run : type "CMD" without the quotes then type "cd\" then enter to go to the root drive. then, delete the virus by typing "del kxvo.exe /a /s /f" then enter. delete the autorun file as well "del autorun.inf /a /s /f" try signing in after you delete the file. Hope this helps.

Re: messenger not signing in

Are you using the latest YM? why not try downloading the latest YM but before installing it, uninstall some unwanted programs or those that you dont use some disk space.

then try installing the latest YM now.

hope this helps.

Actually this happens quite often. I recommend that you uninstall messenger and then reinstall. This will fix the issue. I have actually had to do it myself a couple of times.

You could try uninstalling the messenger and then doing a clean download and install(meaning make sure when you download that all of your running programs are turned off, including your virus control.) Also, you might want to check your virus control under interent content or whatever yours may call it and see if you have been prohibited from using yahoo messenger there. Someone may have accidentally prohibited any chat or messenger programs. Good luck and let us know with a rating. thank you.
Please check the amount of memory you have. The messenger uses a lot.

You should probably do a major clean up of your system:

virus update and scan

start all programs>accessories>system tools>disc cleanup

toolbar>tools>internet options>delete all your cookies

check through your little icons in the lower right hand corner and tell me all that you have there. If you have a bunch of proggys waiting to start up all the time that uses memory, and most but not all do not relly serve any purpose.

Take a look at your desktop and delete any unnecessary icons for proggys you rarely use (this does not delete the program.) Right click on the icon and click delete.

If you have register cleaning program run that

Go through your files and delete junk you know longer need or want or put them onto a CD (I mean old pictures, files, etc.)

Empty your recycle bin

start all programs>accessories>system tools>defrag Good luck and let me know if this solves your problem.
