HELP!!!! I just tried to open my project I worked on about a week ago and I'm getting "The Project could not be loaded, it may be damaged or contain outdated elements." I did not do anything different than before and all my premiere files are saying the same thing.

My drives are fine and all my other files on my drive work fine. It's just all my premiere files. HELP!
