Display switched back to 1024x768

My display switched back to the 1024x768 Resolution, and my other options disappeared. I installed 64-bit Apple Boot Screen and 10.7.2+ Combo patch again with MultiBeast and still only have the 1024x768 option. Am I missing something? It was working fine yesterday and today. Help!
