[Cheat with specialists]

OK, I want to play GR with the specialists from level 1. I have replaced (I think) the "unlocked-heros"-file with a cheat-file downloaded from the Internet. Still, it dosen`t work. I am frustrated. What do I do wrong???

[Desert Siege will not start]

I have finished the 15 levels in Ghost Recon and have installed Desert Siege. When I start the game the intro for Desert Siege appears, but when I choose to play the campain the game starts on level 1 in Ghost Recon, and not Desert Siege. What do I do?
