Tactics Trainer stuck


I keep getting the same problem over and over.I do not know the Problem ID#.

I'm white and the problem starts out with the white king in check but it's says waiting for the computer to move. It waits and waits. There is no legal move from this position. Blacks last move had to place the white king in check.

I close the program and move away from the page but when I come back and try to start Tactics Trainer it's right back to the same problem.

How do I get past this?
