I tried installing v15 and copying the Steam version's IDE into the folder to no avail. v15 still reports as the demo version and the newer IDE has some weird quirks saving files which cause the precompiler to report syntax errors on line 1 regardless of its contents. For some reason the IDE always points at line 2 though.
Opening newer files with the older editor shows up with 3 glitch characters before the start of the program, so I assume it's some kind of bug with Unicode handling.
