I have similar problem. I have MSN 7.0 now. I can chat with web cam about 5 min then I can’t start it any more. Also the sending of files stop. And finally I found out that nobody can’t get my messages but there’s no error messages. I can’t understand what’s wrong with msn. I’ve done already 4 times format c:. I occured same problems with MSN 7.5.
Today I noticed also that my messages don’t go to other users. The same problem occures with MSN 7.0. I’ve done format already 3 times, but there’s nothing changing. I still wait somebodies help. I’m using Pentium IV 3000Mhz with Win XP + SP2.
