I've tried to get my own Portal set up for the Chaos%, but I cannot get it to work properly. The video on here only gives the link to the .bat file, not the AHK file, which is easily remedied, but the .bat file seems to act differently than in the tutorial, possibly due to an update or something similar? The issue I am having is stated in the comments of the same video, but it hasn't been replied to with any solution. It reads: "After selecting my cfg folder, for a brief moment I can see the chaos% title screen before the batch file closes on its own. Any ideas whats going on? Any help would be very appreciated."

Is it possible that the .bat file has had an update, and as such there needs to be a new tutorial? or is this is misinstallation on my end?
