Sorry for the double post but I wanted to add that I have now tried it about 25 times and the error occurs everytime on the same frame.
Today I got this message:
Application has generated an exception that could not be handled.
Process ID=0xc38(3128), Thread ID=0xbb0(2992)
Click OK to terminate application.
Click CANCEL to debug application.
Right now I am going to uninstall the program and then reinstall it to see if that makes a difference.
