Oh, I've also just determined that, while I can't sign in to my own Windows Live Messenger account on the Administrator's account (the one I use all the time), I can sign in to a newly created WLM account. Also, if I try signing on to my regular WLM while on the guest account, I can do so without a problem.

Please, help me!

Might be a bit late but i had the same problem and i fixed it by uninstalling msn then:

Delete the file: C: \ Program Files \ Windows Live \ Contacts \ wldlog.dll


then reinstall msn and try again ..good luck




use msnzapper to save time uninstalling http://messengergeek.spaces.live.com...0&sa=410731844

My Windows Live messenger is still unable to work and this is the message its
show me:
"A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available."

Also other people can sign in using their accounts in my PC but not me. I'm
automatically signed in and my password is saved on the WLM.

i dont have any of they anti-virus, i have spy sweeper. the new msn 9 used to work on my laptop but it just stopped. i tried to download the older msn but everytime i do it just says i have to download the new one. also when msn does start up my screen goes blank then turns all different colours, it goes back to normal when i close msn. please help me!

Finally I found a fix that worked for my Vista Home Premium 64 Bit ed. and the latest update from Windows Live Messenger. This Page shows a few different solutions to a few different problems. Messenger Support Space - Windows Live My problem was with the Nvidia file and when I ended that Process I was able to sign into messenger with this latest forced upgrade with no problem at all!! No More - Windows Live Communications Platform has stopped Working and will now close and look for a solution!! Hope this Helps Everybody Out because this is a very annoying problem especially if you use your email everyday.

Good Luck All
Later
