Hi,
I just purchased DCS: Black Shark today and happened to run into the same problem as well. I've used up almost all of my activations trying to activate the game. I was wondering if anyone has found a fix to this problem yet. Unfortunatly, I don't have another computer to play it on, so I'm stuck with what I have.
When I look at the serial number information on the star force website, it lists all of my activations, yet I still get an internal error message, even though it says is has been activated. Thanks for the help and I look forward to trying out the game.
