I just bought Ghost Recon on a Steam sale. I played through the first level and beat it in a few tries. The only problem is that every time I beat it (3 now) it takes me to a screen that says I've lost. It says all of my soldiers are dead, regardless of how many actually are dead.
I clear out the camp and get a notification that I've finished that portion of the mission. I then head to the caves and clear them out and get a notification for that. Then I run up to the target and have him follow me back to the start of the level. Upon killing all enemies in the area, I simultaneously get notifications that I have completed the remaining two objectives (capturing the target and returning to the beginning). The screen slowly fades to black, and then I'm presented with the screen telling me I've lost.
Because it is not allowing me to win this level, I can't even play any of the rest of the campaign. Any suggestions?
