Disabling 'ComputerTime' without admin access

Just today my Dad installed some retarded program called 'ComputerTime' on my PC which limits my time. So far i think i've disabled it by disabling some .exe that it was running, but i'm not entirely sure. The only site i could find on google to do with disabling it appears to be down, and i could only follow a few fragmented instructions from it.

Does anyone know of anyway to disable this piece of crap? Be quick, i think i've only got 1 hour 30 minutes left before it automatically logs me off.
