Win ME and ICQ Problems

Has any one out there had a problem with Win ME and ICQ not working correctly, it seems as though I can receive a file transfer but I can not send a file to any one, or a url, the only thing I can do is send messages, and hafe of the time ICQ is locing me up. I've tryed to reinstall it , but get to the end and it locks up my computer

Red i have Windows ME and am using ICQ 2000..

I have had no trouble with it except when i use Internet Connection Sharing(ICS) but thats to be expected.

Are you behind a firewall?

Nope no firewall here, I'm useing the latest ICQ 2000c
