If you had the original disc, you could just use a backup manager to rip it to the internal hard drive. What you are telling me is that you've downloaded the game illegally, and want our help on figuring out how to use it. Well, I'm an asshole today and you will have no such luck as I'm going to give out one golden peice of wisdom.
If you are smart enough to pirate the software, you are smart enough to figure it out on your own. If you are too stupid to figure it out, then oh well.
If you need help, post a question in the
forums, not my PM inbox. Thank you.
