Can someone read this crash report for me?

I'm playing Voltz with my friends and i can play for a couple minutes, then i crash and every time i try and come i come back on, i crash within seconds. I got the latest java and have 2 gigs RAM on my minecraft with setting on low. I don't want to stop playing and i don't want to uninstall voltz. Here is the crash log:

I've had some similar stuff happen to me. I turned off my computer reinstalled java ad mine craft and a friend helped reinstall and delete volts it worked after that. Some trial and error and a bit of reinstallation should fix it up

Sounds like an entity is missing that can't be rendered
