Hey Danolo the problem with burning / backing up games is that our burners cannot recreate the disk propperly. The security that the game companies use is based on bad or unreadable sectors which the games need to funtion propperly. That is why when you download a game most likly it comes in some sort of image file like you have now. The best way is simply to mount it as a virtual disk with something like Virtual Clone Drive and it will work fine as all bad sectors are still there where they need to be. There are some workarounds that allow you to use the game without needeing the disk in a drive or the image mounted your download probably came with a crack or no disk image / fixed exe for it.
