Hello

If this is the wrong place to ask for help - I apologise for being a newbie.
I have just started to use Knoppix live CD and I cannot access my CDROM's on the desktop. A message says ERROR - file:/mnt/cdrom does not exist. When shutting down - the system says "cant unmount CD - please reset". I wanna give Windows the flick - but I need to have access to my 2 CD drives. Please help!!
