Replying to PREMIERE PRO HELP!!!

I downloaded adobe premiere pro 7 off limewire with the serial # and crack. I got to the install page, cracked the serial number and it accepted it. Then when it started to download it asked for the disk.... it said I could change the source or something or put in a disk. I was wondering if anyone knows how I could go about doing this. Also, as I was writing this i cracked the serial number again and it wouldnt except it. can you only do that once to the same number? if anyone has any help in this matter it would be most appreciated.
