Slight render problem...

Last night I attempted to start rendering my animation at around midnight and leave it there until I got back, but when I logged onto the render account, Cinema 4D wouldn't start because it said the serial numbers were incorrect. I didn't want to just leave my account open, so I decided to go this morning and render. Unfortunately, I woke up a little later than expected and it's clear that my animation will not be ready by the time today's class starts. In fact it's 11:30 and the animation's not even halfway rendered. I'm not sure what can be done about it at the moment, so I'll let it render for as long as I can and see what happens.
