Ah yup that did it! Thanks so much for the help.
(I do still have this strange issue where copying anything, with ctrl+C or the button in the edit menu, crashes the program immediately. Strangely, even after re-installing, this happens on my desktop pc, not my laptop. Not a big deal, I just use it only my laptop, but let me know if you want the crash logs or anything. I'm guessing this doesn't happen to most people so not too worried about it.)
