Working with P4 and update installed. I tried a render at 900PX-72res. and got a message of insufficient disk space. I have an 80gig hard drive with 256dram,Pentium 4. Now is this related to memory? Can't believe it's disc space as I have 70% unused. Even shut down pc and did disc clean and didn't help. Did the render at 750 before it would work. Any ideas how to fix this?
