Ok, here's the newest version of CCOA's UMS. I uploaded it for you.
When installing scripts, such as this one, open up the demo-->go to tools-->script editor-->then copy the script, and then simply paste it into your game. When you past it though, It has to be below Scene_Debug, and above main like it shows in her demo. It should work if you do that.
When you don't have a demo, and just code, you do the same thing, except you have to right click in the script editor below Scene_Debug and above Main, and then select insert. Then click the blank spot you just made, and paste it into the window beside it on the right.
Hope that helped and good luck. :thumb:
