once u get the launcher thing patched over etc, u need to launch the 64bit version from the file, not directly launching it from steam. that just causes errors or boot loop, or my game didn't even open it just limbo'd however. launching the 64 bit once the retail file was inserted, it works just dandy, the money code seems to not work, but 999 of the one material u get to vendor is worth 100k each, so at 999, its doable.
