I don't think you can get it running at this time without actually buying it from the PS3

Correct.

An unique license file is created when the title is downloaded from the PSN. The game will not run without it. It requires a firmware-side hack to allow it to work without a legit license, but currently none exists.

So in short, sorry, you cannot run this game without buying it off the PlayStation Store yourself. Closed.
