Nero Express 6 question

I am trying to backup some data files using Nero Express 6 on a CD-R. Last time I used Nero Express I backed up my HD using a DVD+R.

When I go to “add files” to copy on the CD-R, Nero is looking for DVD media. I go to burn the files and it asks me to put in a proper disc (a dvd disc).

When I look at “disc info” in Nero, it is seeing the blank CD-R in my drive.

I’ve been all throughout the settings on Nero Express 6, and cannot figure out how to make this go.

Any help is greatly appreciated.
