Problem burning CDs on a Rimage robot

I am working with a Rimage 2000i cd/dvd robotic burner.
It has 2 Plextor DVDR PX-716A burners and a Rimage 480i Printer.
The SW version of the production engine is
For cd-editing SW I use the supplied Quick disk ver.

My problem is that I cannot burn CDs, DVDs work fine. When I try to burn CDs it comes back with an error message looking something like this: “Media code 97m34s23f is not allowed”. The number varies with the type of CD I try. I have realised that this number refers to the make of the CD

Anyone who can point me in the right direction?

Stupid me. The option “use only specified media” was set on, can’t see how that happened, works fine now.
