Microsoft Security Essentials Error Code 0x80070005

I was surfing the internet when the tray icon for MSSE turned red and told me that the service was stopped. When I tried to restart it, it said "Access Denied". I am running Windows Vista Home Premium SP2 with 3gb ram. Here are the results of the accesskchk.txt:
