title is self-explainatory. Downloaded the file and inserted it into the "Scriptable Auto Splitter" and checked the box.

Yeah, the autosplitter sucks and certain things don't work on different PCs. I gave up on fixing it at the moment, it's difficult to debug since it works perfectly for me. The only thing I can say is if you reboot a bunch it might work. Sorry

Though if you (or anyone else) happen to have experience with making autosplitters I'd be glad to work with you to get it fixed
