Whenever I try to zone into South Shroud (whether through Duty Finder for a Guildhest or directly from the map), my game freezes and crashes. The screen goes blank except for the chat box, with which I can still interact for a minute or 2 before the game crashes with a "(2)(45d)" error. I'm able to zone into South Shroud on another PC, so I think that there's an error on my computer. How can I fix this? Is there a way to check the files on my PC and repair broken/improperly installed ones?
