Just DLed and burned my Knoppix CD, v3.9

When I boot I get this error:


"Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit."

I DID search the boards but didn't find anything.

Here are my specs

burned CD using Nero
3.0 P4
1GB PC2700
XP PRO

Any suggestions are appreciated.
