The only thing you must change to go back to playing live is your EQ shortcut.  It probably reads something like 
	Code:
	C:\Program Files\Sony\Everquest\eqgame.exe patchme
  Just change that shortcut back to read 
	Code:
	C:\Program Files\Sony\Everquest\everquest.exe
   Please note that the location of your Everquest directory maybe different than mine.
Sorry to see you go and good luck on live.
