I have a problem with the latest beta version, R185. I needed to update to the beta version (because of the popups URL blocked by browsers). Everything went good, Friday I saved my project to my Google Drive cloud account and went home.
Today, I wanted to make a change to the game so I opened the project from my laptop (not PC), but I got the following message:
"Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project.".
I tried to downgrade Construct 3, but if I do so, I will get another error telling me that the project was saved in version R185, and I'm using R182 - so, I need to upgrade to R185 again.
I can open other project saved in other version of Construct 3. The single problem is at that project saved in R185.
Anybody got a trick? :)
I tried to get an older version of the game project (Google Drive > Manage versions), but it won't open it. I got the same error. I tried to open the very first version (that was in 31 January), but I got the same error.
