Wow, that's lots of stuff. I think your memory is a bit low for that kind of project. I have 640MB of RAM, and don't dare get overly ambitious. It would be nice to know about some variables that would make a difference: 1.) What render settings did you use? (A screenshot would help). 2.) How much free hard drive space do you have? 3.) What operating system? 4.) Any other programs running at the same time?
