I have my main character, I was running toward the bank on DS9, and had a crash to desktop. Oh well, restarted the game, same thing. Rebooted the computer, same thing. Ran the check files, logged in, same thing.
Changed characters, and didn't have the problem. Loaded STO on a *different computer altogether*, verified the computer, logged in, THAT machine crashed, with entirely different hardware.
Something about my particular character in that particular place has me broken. Help!
Three times I crashed logging in at Qo'noS. I finally managed to get ingame and beam to my ship so I flew to Deep Space Nine. Then I had to log for a while and, when I came back and logged in, I crashed. Like you, it appears to be just the one character.
So it isn't just DS9. It's at least in Qo'noS, too
