Cheat Engine

[Niko]

I'm wondering if anyone could help me unlock the exclusive pre-order skins for the game aliens vs predator 3 (2010)? I've found a way to change the selected skins to the locked preorder ones, but I want to fully unlock them. I can also sort of change my rank to 44, (43 is the max rank, I'm not even sure what the address I found does, but it changes my and everyone else's rank who is 43 to the value I have selected, this is not visible to other players) and that unlocks the skins if it's 1 over the max rank. Also if I decrease that rank value skins begin to get locked. A problem is that people who pre-ordered the game had these skins regardless of rank. Any help on this would be appreciated. Note that the files for the skin are by default in the game, just locked to people who haven't preordered, you can also change your selected skin to them with cheat engine. Also the game isn't Vac secured or doesn't have any other anti cheat. Thanks in advance to anyone who could help
Also that rank value I have is a static address that I sill post if anyone is willing to work on this. I have also found the differences between the locked and unlocked skins by changing the rank, however if I nop out the code every skin is locked. I don't really know what do here. Freezing the addresses also doesn't work.
