Service Status: All systems running
The connection troubleshooter found a problem with 'hosts', so I repaired it. Unfortunately this hasn't fixed the problem
The MSN Messenger version is 7.5.0311.
Thanks for the help so far guys, anyone have any more suggestions?
EDIT: I've just tried 7.5.0322 and that hasn't worked either. I've also tried re-uninstalling Messenger Plus! and there is one file I can't get rid of: MsgPlusLoader.dll - could that be the cause?
