Help! Can't change TFT cd-key!

[dyablohunter]

I recently bought a copy of TFT, I installed it...it has 1 week now. I just decided to play on battle.net but I don't know what I did to the game with cracks and stuff like that, it won't connect because of the cd-key, I would try to reinstall it but my original CD exploded in a friends CD-ROM (seriously), I still got the case with the original key but I don't know how to change it, I tried a cd-key changer and it says something about... Can't calculate the free disk space on drive I:. Setup needs at least 256k to complete the instalation.
I tried to modify the key with regedit, but I didn't find the location of the serial entry, can anyone tell me what should that location be? where I could find it with regedit? or how to fix my problem...
I just feel like dying when I see : Could not connect to battle.net, your CD-KEY is invalid.
Please Help!

You have to call the manufacturer and if they deem that you truly do have the original game, they should be able to tell you the legal way to change your key.
