It must have been a faulty download, I redownloaded II and III and they work perfectly now.
Watched episodes I and II this weekend, loved them both so much- especially II. The romance was so much better, the Jedi don’t seem like complete idiots, Obi-Wan doesn’t look like such an a hole to Anakin, and you removed the Yoda lightsaber fight! I always thought he should be above a lightsaber duel.
Looking forward to III tomorrow!
