Well, incase you still have this problem:
1.) relog
Now you should be in the same dead zone but with the UI.
2.)In the chat window, type @go fm
VOILA. Enjoy.
If this doesn't work, do these steps:
1.) Enter the main site:
http://69.162.166.180:41/?butsags=main2.) Log in.
3.) Now, you should be in the control panel's main menu. Click control panel. LoL.
4.) Now click Character fixes > All-in-one teleport manager.
5.) Now select the character that is black screen'd, and click "Warp!"
TADA. now you should be in FM (You can also select another map.
)
