Project is corrupt or invalid
Good morning. I have recently had a Storyline project I've been working on for 6 months become corrupt. Our IT team working on my computer for 2 hours last week to try and repair the file - to no avail. The 'corrupt or invalid' error message has appeared after displaying a different error message for a few days - 'this file is being used by another process and you do not have the proper security permission to access this resource. Make a copy of your file and open the new file' (see the attached pictures). This worked three times, and then it became corrupt. I do not have an up-to-date copy of this file that is not corrupt and am facing losing 6 months of work. I would appreciate any help anyone can offer. Many thanks.
