Is my Garageband finished?

I keep getting the "Part of the project was not played" message. I've looked around the internet and found a lot of people had the same issue and no real solution. I've tried optimizing, muting tracks etc. Is this the beginning of the end for garageband on my computer? Please don't answer with a question.

Thanks
