I cannot re-edit after downloading.I was making it for my google adwords campaign but it says " Flash performs disallowed operation - Random Number Generation" when I upload it.Can you tell me what options should I change to resolve the problem.

I cannot re-edit after downloading.It would be great if one could register on site and save the project and make any changes if required.I was making a banner for my google adwords campaign but it says " Flash performs disallowed operation - Random Number Generation" when I upload it.Can you tell me what options should I change to resolve the problem.
