QTR-Quadtone RIP

Hi yet again.

Okay, so I think I solved my first problem. 

In System Preferences, I simply made a new printer, appropriately named. Doh! Then the script worked, but said it was "unable to create curve folder." I just made that manually and ran it again, and that seemed to work (I used copied curves from the R2880 folder, as the R3000 folder was empty apart from the script - hope that's right?). 

Now QTR comes up, and the profiles are present. Good so far. 

Now I've hit another snag. The printer keeps telling me "The media loaded does not match the settings selected." Seems no matter what I try, both from Aperture 3 and the new QTR Print Tool (which worked great for colour) nothing is happening. So, either I'm not doing something right (chances are), or the install didn't go as smoothly as it finally appeared to. 

Any ideas? 

Thanks.
