I was given a hard drive with a Premier Project file to work on. It's a pretty large file (119.5 MB) and I keep running into the "This project cannot be loaded, it may be damaged or contain outdated elements" error message. It doesn't matter if I try importing it from File > Import, File > Open or through the Media Browser. I've tried importing the entire project as well as just importing sequences, with no luck. I also tried messing around with memory allocation and gave Premier a little more RAM to work with (4 GB instead of 2 GB). My MacBook Air only has 8 GB so I feel like that may be part of the problem? I have no idea, I'm fairly inexperienced and have a deadline coming up so any help is appreciated
FYI, this just happened to me on a project that I've worked on since the beginning of the year. Tried what all the other posts suggested as "Solved" to no avail. Cleared cache, reset (alt + Open), tried to import sequences to new project, etc. No luck.
Finally, I re-installed the previous version (15.0.0 (Build 41) and it opened.
