Ok so here's the problem. I played the Dupliess Diamonds level and beat it 5 TIMES and when I open Swat 4 again it's still stuck at that level. Thing is, if I play past that level I'm fine, I can keep playing. So then I shut down my computer and when I start it it's stuck at the diamonds again! Having played that mission oh about, 20 times I would be grateful if someone knows a solution to this. Thanks!
