Well I have run numerous virus scans etc and that doesn't seem to be the problem. Like I said it can be fine for a few hours and then I'll get disconnected, and then the constant G-Line message will appear.

I'm using a 'web n walk' connection which means I'm not on a network, but my USB modem uses a phone signal to connect to the internet. Could that have something to do with it? mIRC has been fine for weeks though, and only in the past few days has this error appeared. frown
