I updated to 1.3.0 but then I saw the server is in 18.104.22.168 so I returned to that but I am crushing. I disabled full screen but it didn't improve.
Are you crashing as soon as the client launches, or when you attempt to login? That crash report points to Draconic Evolution, which shouldn't be related to the game being in full screen.
If anything, try removing the mod CustomMainMenu.jar
btw, the server will be updated today at 5p. I also encourage bug reports to be submitted to our website's forums, not here.
