Sorry to hear you're still having problems, but in addition the steps Karen has already suggested, I would strongly advise a virus scan. If you're using a pirated copy of XP you have no idea what's loading in addition to the OS - you said yourself it has a registry crack built into it. Furthermore, if you're now getting disconnected daily, I would take that up with your isp. I'd even go so far as to say get rid of XP and reformat your hard drive, and get yourself a new, unpirated copy of Windows whatever. Then do a clean install of mIRC once you've sorted everything else out. Warez are dangerous, imho. I very much doubt your problems have anything at all to do with mIRC.
