Just a note that trying to put the IMG and unlock file on a 4GB FAT32 using a Mac OS didn't work. Switching to a PC, deleting the files on the card and then putting them back resulted in a working card. Also, unrar on Mac and the file size is about 1.85Gb. Moving the same file over to a PC and the file size "changes" to about 2.22GB. So the IMG did unrar properly using a Mac, but installing the files using Mac (OS 10.6.4) doesn't work, have to use a PC.
