Hmm... never a dull moment, eh?
Try going back to DarqUI, but in your custom folder delete eq2ui_mainhud_shutdown.xml
before logging in. That's the only place where the UI explicitly uses the /camp command. If you are still camping in error after deleting that file, check for any custom macro or hotkey commands containing the letters "camp". Please post back with your results -- this is an interesting one.
