I got a big problem with Joli Cloud OS.

I downloaded JoliCloud OS and created a Live USB. Booted from it. Then, at the boot splash, it says Configuring Nvidia Drivers... The screen flickers for a little while. Then, the text goes out, just splash screen. Now, it does nothing. I wait 10 minutes, but still nothing. Pressing Esc hides the splash screen, but it says now this:

X: Fatal error:
No screens found. ---> WTF???

Can anyone help with this?
I really need Joli Cloud OS now...
