Msn has stopped working :(

Hi guys,
I know this has nothing to do with flash but hopfully someone has experinced this problem.

I cant seem to login to MSN messenger. I dont get an error code or timeout code. It just spins saying logging in. The funny thing is during this time if any emails land in my account i get the msn prompt to say that a new email has arrived.
I have tried un-installing and re-installing but with no luck.

Has anyone else had this problem? or does anyone know where i can get an ealier msn messnger version to try.

thanks
Paul
