You can try a clean install, there may be some corrupted files of some sort causing the problem. Could also be other software on your computer, so closing any running applications (security especially) would help.

hi ive been in at add/remove and took all the windows live components out im using nod32 and zone alarm for firewall ive added windows live messenger to exceptions tab on zone alarm what version of windows live messenger should i re-install thanks

You should install the latest version of Windows Live Messenger from here

thank you will download and post back

What error code does it give you?

it gives appname messenger exe  appVER 14.0.81.17.416 apppstamp4bc935a
and a lot of other weird numbers

Post a screenshot of it?

When EXACTLY does it happen?

Did you try the clean install suggested by Chris above?
