I've been poking around with my old old RMXP project, and decided to feed some scripts into it, to make it prettier. I wanted to use a message system that'd let me use facesets and name boxes, and Slipknot's was the only one I could find. I ripped it from the demo, and put it into my game, and I got a popup error.
Script 'Slipknot Message System' line 18 NameError Occurred
uninitialized constant SDK
I'm using version 02.23.06. The other scripts I have are Akxiv's Level Up Box, Fukuyama's Caterpillar Script + Mr Wiggles' Full Screen Prompt script.
