I dont really think that is the problem and dont think that is true, seeing how when you reg mIRC the key is stored in the system registry. So even if you deleted miRC and reinstalled next time you opened the new mIRC it would continue to act like it is registered. Also, mIRC doesnt have a way to see if the key you have is infact not stolen, some things now a days have a server database that stores who has what so if you use their programs it will check with the server to see if it is infact registered. mIRC doesnt have this feature. Also, this is just a theory, I dont know, I notice that the reject notices have been happening to me after the release of 6.12, I was able to get dcc's fine before this version, I am thinking it has to do with the dcc exploit fix, maybe something wasnt coded right so it created a new bug with mIRC's dcc to make it think it was the exploit?
