CC files – File not saved... or obliterated

Hi there, I've seen other posts but nothing exactly like this...

I'm using the CC storage for my projects, a "work in progress folder" and the second one for safety once I'm done with a sprint.

When I opened the file I modified this morning, it was a version that was 1 month old... It is not among the deleted files and there is no "conflict" version...

Please tell me there is a way to get it back...

Thanks
