Are you playing on Linux by any chance? People have reported some issues on that.
I am. I run rpgmaker games using rpgmaker-linux.
The demo version runs perfectly.
I have heard it works when using "bottles"
Thanks. Bottles is a good suggestion, I'll try that if I can't find a better way. I have had more issues with RPGMaker games running via bottles than not, so it would be interesting if it works better in this case.
