It is working now. Thank you soooo much to both dop2000 and akabaru48.

Ok I did it, so do I now go and reload construct 3 to its current version and open the project and it should hopefully open?

Should I also edit all the layout names to not have any spaces and have _ instead like Akabaru48 told me to?

Should I edit the space error directly from the notepads code?

And also, I cannot find the words in the notepad : "SavedWithRelease when I cick Ctrl F and search for it.

how should I convert the SavedWithRelease code into a v. 7of my game

I unfortunately have a problem: each version which has " Playership Start screen Layout" is also doesn't open.

I don't have enough room for one screen shot so this is them all

Thank you very much

Hello, recently I was working on a construct 3 project and I saved it in the evening and in the morning I got this message saying : "Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project" I have read other peoples similar problems and I have extracted from a zip file and clicked on F12 next to the message but I don't seem to know what to so next.

I Have saved this file on drive and it is the v.7 of my project and v.6 and v.5 also do not work but v.4 does.

Does someone know a way to resolve this?

Thank you
