Even if its old, it is still working. i played with it without turning it off in the lobby and i still didnt d/c when i went to another room and play. and all i did was:
1. Set CombatArms Compatibility. ex. Windows 2000 or Service Pack 2.
2. Open PerX w.e its called and put D3d9.dll w.e its called and also the TnT.dll You dont need a bypass for some reason.
3. Open Ca And Play.
Its that simple and it worked. I dont knoe if it works for you guys but it DOES work.
