Hi, I am currently trying to render out one of my scenes for uni with the maya software. Some reason I set the start and end frame but it keeps doing a few hundred frames then it says its completed?

Its a pain because I really need to leave it over night because its going to take hours and its got to be handed in on thursday.

Anyone know whats going on?

Its maya 7.
OS: Windows XP

Intel Core Duo T2500 (2.0GHz)
ATI Mobility Radeon X1600 - 512MB HyperMemory
2GB RAM

Its a laptop lol

Thanks in advance.
