Well how much free space do you have? I had a similar error once and could not figure it out so I checked it with file explorer. Yup the disk was full. The swap file consumed the entire drive on a huge render I was doing. Now not saying that's your problem but after you create your animation. Save it quit Vue reboot, turn off crud and load Vue and render away. Now you'll tell me your on a Mac. I personally can't help you then. Remember lots of files don't show on a winders box that are there depending on how you got your box set up. Beware of that wierdness. Like the trash can takes up 10% of the drive even if it's completely empty unless you change it settings.
