I had this problem myself with Lower Jueno => Port Jueno. I zoned, went to loading, and crashed. Tried relogging, crashed. I did a file check, and it found nothing (and froze a few times), so tech support informed me that reinstalling was the only option.
Honestly, it's one of those things you might not want to hesitate with. I mean, you could wait a few days to try and find a solution. But you may not. You reinstall now, you can play for those days instead of taking a gamble. Would suck to wait and have to reinstall anyway.
