My project will not save.

I am working on a logo for a website. The most recent draft I made was approved to be sent to some group for further edits. I attempted to duplicate the file, saving both in the process, but then I was automatically logged out of Adobe.

Upon logging back in, the project had reverted back to a previous draft from two weeks ago. This does not take much time to fix, but then when I do fix it, the changes are erased once more. The autosave function never completes, and when I finish working on something, I can download it but if I leave the app/webpage, all updates will disappear.
