Forums General Discussion mirc folder

That's what the server you are connecting to says. Just try it without and see what happens. If that's the cause, you can always complain to them. It has nothing to do with mIRC or the mIRC registration if the network (or a server on the network) has specific rules for what is allowed.

* Note, "username" may refer to your identd/email and not your nick. Check your identd settings and email. It may be that you have it in there on one install and not on another.

EDIT: Looking more closely...


So yes, it's your identd (or email if you have identd set to use your email). On your UPP version, identd isn't on or isn't working (it says no identd response), so it's not giving you the problem.
