You're telling me Construct-2 isn't backwards compatible? Oh, well time to download Construct1 then.
Edit: Okay so I downloaded Construct1, installed all patches and stuff I could find. Try opening the .cap, it'll load till 5% and then says
Error with loading: expecting class (CAnimation), but recieved ()
Fantastic. Not only is construct not backwards compatible it doesn't load things properly either for me.
