I have just reinstalled my Computer with MSN Live Messenger 8.5, but it keep disconnect and reconnect damn piss-off.

Finally found a solution to have this solved.

1. Exit your MSN
2. Go to Run, type %appdata%\microsoft (for vista, type at the “start search” column)
3. Then press enter.
* A window will open with some folders
4. Right click the “MSN Messenger” folder and Delete it.
* Don’t worry, this folder have nothing important.
5. Run your MSN again.

Good luck.
