hmm i feel sorry to make such a big discussion. Well i just only wanted to know the key in the registry (or if the identifier already exist).
I don't wanted to find a way how to crack it or other things (when i realy want to do something like that i would do it and not asking in main mirc board).
It should just stop using of unregistered version of mirc or well the main background i don't want that every lazy kiddie use my script.

that was all i want and i repeat "I don't want any illegal things"
