I've tried launching, using the "force recompiling" option, deleting the original script, and yet, I have no idea how to actually playtest if there's no .exe for where my modifications go, of course. I'm not sure if it's because the folder is invalid ( before re-installing RPY, I had it in my Ren'Py folder, which I now deleted - it used to be in my Downloads folder on the D: disk )
If anyone would help me, that would be very much appreciated!
