I have a GS3 Performance File won't open on my computer. Each time I try GS3.1 quits. It worked fine yesterday, and I've noticed a number of my other performances will not load. Anybody? Do I have to rebuild it manually or is there some way to rebuild it with GS3? If you're willing, I've uploaded the file to: http://www.codywestheimer.com/gsp.zip

Any help would be greatly appreciated!
