You may wish to use the Search feature, there was at one point a spurt of posts with people saying that they were experiencing this error message. I don't know why it is only mIRC being affected. When using the search feature, expand to 'All Forums' and 'All Posts', most people were helped with their issue, their solutions might be yours too!
Have you tried closing all programs before opening mIRC? This includes the ones in the tray, often MSN Messenger, Antiviruses (
temporarily), AIM etc.? Did you do anything at all before mIRC Stopped working? (e.g. download any programs, even if you didn't install them, windows updates, ISP changes etc.) Make sure you're using the
latest version of mIRC, and also try connecting to several different networks.
