Hello, recently Construct 3 updated to r317 version, and the next day the following error started to appear every time I try to open my project: "Construct 3 Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project."
This is a 3 years project, and I always kept 3 different backups of the project, one in the cloud, one in the dropbox, and one as a local file. After the update, they all fail to open. I already tried to go back in some old versions of Construct 3, but it keeps giving the same problem.
Does anyone know how I can resolve this? Please?
