I've been going through the Getting Started examples in the demo of v22 and can't get the simulation to work. When I try, the simulation window pops up, but all I see is a beige background, and when I hit play, nothing happens, and the progress bar doesn't move or anything.
I know I have toolpaths since I can see those in the main window, and I've tried to follow the whole thing step-by-step. Are there any "gotchas" that aren't in the documentation or something else I need to know about?
