I have not much time, so maybe someone else will help you further but for now:
- Make sure you have downloaded the latest version of WLM 9 (there is a new version):
http://messenger.live.com.
- Uninstall Mesenger Plus! to make sure it isn't the culprint of this issue. Although I'm 200% certain it isn't.
- Whatever you do, or what someone says, do not cripple or trick wlcomm.exe into not running. There are several "fixes" suggested by people who tell you to remove it or rename it, etc, but that will only cause you more trouble in the long run.
- It is normal that it takes a while for the "Windows Live Communiations" error to come up. That is standard Windows behaviour to tell you that something has crashed because you 'killed' wlcomm using Task Manager. Some other component of WLM was still trying to use it and after the timeout finally showed an error that the program crashed.
- Try to reset your contacts cache folder:
