I saved a file last night that will no longer open on any computer. The previous version, also saved a few hours before that one, works just fine. I put a massive amount of work into setting up the CC data (orchestral score; 8 mins) in the most recent file and am afraid re-doing will yield the same result.
Is there a way to edit something in a zipped file within the main file to fix this issue?
What has triggered this failure?
Thanks so much for you time and help.
UPDATE: I save frequently and recovered the version from only 30 mins prior, so not too much work lost. However, the questions still stand so that I can solve these problems in the future. Thanks again.
