Basically, since the start of the month, I have not been able to log into MSN Messenger. It keeps coming up with 80072745 Error Code, which I have traced back to NOD32. As soon as Nod is uninstalled, it connects again fine. NOTHING has changed since it was working fine last time (except updates), and it is starting to **** me off. Firewall settings haven't changed etc and I have tried all known measures recommend. One moderator has mentioned that "It could be that your firewall is blocking ekrn.exe on the port that Messenger uses to connect." Not sure why it would suddenly block that port after working fine all these years, but if so, how do I go about correcting it..? Someone please help me sort this out, because I have had to use AVG in the meantime.. THANKS IN ADVANCE!
