The money you paid for mIRC has nothing to do with channel/network registrations. Those are free and are done using whatever services the network uses, such as Nickserv. As your post indicates Nickserv is unknown, there may be some other service handling nicks. I'd recommend checking in the #help channel about that.

Also, if you copy/paste the exact authorization request here, it would help.
