Yeah, I re-validated the files and everything came up fine. I'm going to lower the graphics, see if that does anything.
Alright, so update:
I lowered the graphics to recommended, and on my hero character everything was fine. However, once I tried loading into Port Oakes as my villain character-- I crashed to the login again. I thought he was corrupted, so I decided to remake him. After the tutorial though, I crashed to the login while loading to Mercy Island. Unsure what I should do now..
