I bought episode 4 about a week and a half ago and when I went on today for the first time to play it, dl'ed the update and went to continue my game I couldn't. It says I don't have episode 1 installed and need to buy it from the store even though I have it. It says 2 3 and 4 are installed but not 1. What should I do?
Btw I never got any message about a corrupted save file. I didn't even buy episode 4 until about the 18th or 19th, days after the patch came out.
