If you have already patched there is NOTHING you can do other then wait. the system restore is a way around it, but what there not telling you is is restors your whole HD back to that point so you loose everything you did after that. If you did not make a back up copy of your entire EQ folder you are SOL, just be patient and wait for the Devs to catch back up.

EDIT=

scrubj the easiest way to make sure you can play on both live and EQEMU is to back up the entire EQ folder once you know it works with the EMU, then you will have 1 that you play live with and 1 for the EMU. For instance I have 4 EQ folders, 1 for 4.4, 1 for 5.1, 1 for 5.2(or whatever is the current) and 1 for live. This way I will always be able to play E<U and live.
