I always save my C3 files to dropbox. Today I try to open the project I am working since time ago and after a short time loading the file this messague appears:
Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project.
Yes, the file is c3p. I try to download the file from dropbox to open from file but I get the same messague.
Is something I can do?
