I'm working on a piece for a competition.  The scene has several figures and a large prop, and a large scene/bg. Everytime I render I just get this message.

"There was a problem during render.
when using firefly you can reduce memory usage by rendering in a separate process, raising the adaption threshold or specifying smaller bucket size."

No matter what I do I cant seem to get the render sorted.
The image must be 1024x768.

Has anyone else encountered this....how can I fix the problem. I have a 64 bit machine, ATI Radeon 7000 card. 1GB ram.

Thanks for listening
