My recommendation is to try a clean install of the client, then run the updater.
If that doesn't resolve the issue, create a new char, and create a petition to the GM team using the new character to have your other character moved somewhere in the DR or something to see if that fixes the issue.
*Edit*
oh, and one more thing to try. reboot windows, as something may be stuck in memory that isn't closing right, and is causing problems.
