The problem here is presumably that forward slashes are being used when Windows needs backslashes. The way to solve this would be to use os.path.join() with saves and then the save name.

Thanks for confirming. Yeah it does sound like the classic slash. Hoping to look at this soon.

This almost certainly extends to loading games as well.
