Oops - sorry bout the confusion. I haven't got MOHAA in my possession, the game I used to test what I said above was Serious Sam SE (which has the same SD2 version as MOHAA). That's the reason I'm guessing why you shouldn't have a problem.
I can't see a reason why copying the MOHAA 0000002.tmp file would be any different than copying the Serious Sam SE 0000002.tmp file saying as they're the same protection version.
But other than that I can't really help you.
