need help with unsafedisc

[LEIGHDUFFY]

i am using unsafe disc to remove the protection from medal of honor allied assault
i have copied the contents from the cds into 2 folders on my hdd
i used the 3 programs which come with the download (2_51_Rebuilder, Rebuilder & Dumper) and tried every file when they ask you to open a file
all i get are 2 errors....
bad pe structure (delete it!!)
stxt774 api jmp thingy error, get in touch with me

despite this - nothing has changed

what i woul like to know is what these errors mean and if some1 could explain how to use this program i would be very grateful!
