Ninja program stops working.

I received this notice yesterday and today while entering sweeps in the "My Sweeps" area.
"Windows Ninja Software has stopped working"
"A problem caused the program to stop working correctly. Windows will close the program and notify you is a solution is available."
don't know what to do since I can't enter my sweeps. - Jerry
