I'm sorry to hear that the editor didn't work for you! I have had a couple reports that it wasn't usable on machines with older GPUs, and possibly with issues on Windows… Regrettably, I hadn't had time to do any cross-platform testing before launch, and it shows.
Thanks for taking the time, and I'm glad you enjoyed it! I also hope you'll give DragonRuby a try — it's a lot of fun. :)
