When I click Pattern Layout, it crashes. I have yet to test if this is a crash or it "thinking", I'm not sure if that is the correct term. However I have just resorted to using Pep Designer to rescale and export. The issue I find is that I have to re-unfold parts. Please help, I've tried updating and reinstalling.

Just did a test, I let the program run for 20mins and there was no sign of it changing.
That's quite strange, it's likely something wrong with that file. If you want to send a copy of it to thearmoredgarage@gmail.com I can try to see what's wrong with that particular file.
