Win4lin Pro installation problems

[Marc]

    Hi I am new to Kubuntu and although I have used Mandriva linux for a 
couple of years I am by no means a Linux guru so I am probably overlooking 
something simple.
   I have been trying to install win4lin pro on a fresh installation of 
Kubuntu dapper 64 bit. It all goes well until it is time to load the windows 
cd.  At that point I get a error message that reads "You do nor have 
permission to read from the CDROM device you selected. Please correct this 
permission problem or choose a different CDROM device to read from."

  I have checked the permissions and they seem to be OK. They are set so 
owner, group and others can view content. I have also tried several paths.
/dev/hdc,  /cdrom/ and others but I always get the same message.

  I have to run several windows applications for drafting and schematic 
drawing or I would not  really care. 
   Can anyone here point me in the right direction.

    Thanks in advance
