I have no idea what Mirc tckg5 is or what it does.
It sounds like it's a program that has mIRC included with it (which, I believe is a violation of the distribution rights for mIRC)
That aside, karaoke based questions have been answered a lot. Do a search on this forum for the term karaoke, and you might find your answer.
In any case, you do not log into mIRC, but rather you use mIRC to connect to an IRC server, which, in turn, may offer you the option of using a registered nick with a personalized password.
The karaoke chat rooms may require you to be using a registered nick, but that is up to the room ops, and we have no say or control over that.
I'm at a loss to be able to help you, as you haven't clearly identified what kind of problem you are actually having.
Can you not connect to the server?
Can you not find the karaoke chat rooms?
Can you not join the karaoke chat rooms?
No matter what kind of problem you are actually having, there should be some kind of message in your status screen giving information regarding the problem. This message may be very general, or very detailed.
