Hi all, apologies not sure what else to do or where else to post this - I have just started using Construct on a new PC, and I can no longer open any of my projects. I get the error "Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project." This is the same for every .c3p file, and the same message if I extract and try to open from as a project file.
I only use stable releases, and there has only been 1 update since I last opened these projects (268 - 276.2). I am using same O/S and same browser, and I use no 3rd party plugins. It feels like this must be something to do with my new PC, but I don't really understand what. Can anyone help?
EDIT: I've tried this on over 30 different projects with the same result. I've tried it on Edge and Chrome, same results.
