You should post which client it is that you are having trouble with. Also, check the wiki to make sure you are using one of the correct versions of EQ for EQEmu:

As for UI errors, generally that would mean you either installed a custom UI, or you installed EQ over an existing EQ installation. Unless you either install EQ to a NEW folder, or uninstall EQ completely and delete the folder for it and then reinstall, there is a chance you will have files remaining from a previous install that will break your EQEmu compatibility.
