Hi to all on the Construct 3 forums, I hope this is the right section for this as it is the first time I have used this forum.
So I am working on a 2D platformer game for an assignment at college and recently when I have tried to load my .cp3 file it says "Failed to open project. Check it is a valid Construct 3 single-file (.cp3) project."
As I am saving the game as a .cp3 file each time I have plenty of old versions to check when the issue started to occur and I have found that the 3 most recent saves do not work, trying to load them throws the error I specified.
I have tried to load the project on my windows 10 laptop (with 8 GB of RAM) that I have done the majority of the work on, including creating/saving the 3 'invalid' files on, and my old windows 7 PC (with 4 GB of RAM) and Construct 3 gets to 0.3 or 0.5 percent before throwing the invalid file error. I will try tomorrow at college to see if the issue is somehow 'home' related but I cannot see how it would be as the 4th most recent version (and all prior versions) still works perfectly. I will post an update after college tomorrow to tell you if it did not work there either.
I will put a google drive link below for the .cp3 of the most recent 'broken' file so you can try it yourself, maybe someone here can load it up to find the problem or modify it in some way to fix it, any help would be much appreciated as I have put a lot of hard work into it and am worried if I redo my lost progress it will happen again.
Some info about the game: It is a 2D platformer inspired by the 'Somari the Adventurer' bootleg game for NES (yes that one). The level I was working on before it stopped loading was called 'Flying Aces 2' a vertical scrolling shooting level that I now plan to remove as I no longer like it, could the event sheet for this stage have an error causing the invalid file error? All of the graphics and sound have been re done by me, (redrawn or altered instrumentation)and they were uploaded as .bmp files (small ones mostly) and .mp3 files (oddly large ones).
Hope someone can help me with my problem and sorry if this post is missing some important details or is in the wrong section,
Thanks in advance,
