Failed to Open Document

MK, i have Flash MX 2004 Pro at home, and i used a cracked version of the same program elsewhere, i transfered the FLA files to my home system and it can’t open the files, the program says “failed to open document” with no explination, i also tried to install the use the cracked version at home i get the same results as using my purchased one, the FLA files are not corrupt and they work fine transfering back to the system with the crack, is my problem because the cracked program somehow creates FLAs that are incompatible when transfered to other systems? and if so how can i access this at my home computer now?
