BENNIGELING'S PROFILE

I really hope one of you can help me with this.
Every time I try testing my game an error message is displayed.
Unfortunatly all it says is "????????????" so I have no clue what went wrong, it worked hundreds of times before with the same game and I didn't change anything but the usual map,event,etc. stuff.
What ever I tried, it did not work.
Please help me out.
Thanks in advance
