Playing Lineage II on Windows 7 (GameGuard fix)

If you've tried to play Lineage 2 on Windows 7 you've probably been bummed out to find that you get that pesky "GameGuard" error that has been plaguing pretty much every game in Windows 7 that uses GameGuard. There is a solution that works for both Aion (not sure if you even need it anymore, they may have patched Aion) and Lineage 2, and probably any game in Windows 7 that needs GameGuard.
