QTR-Quadtone RIP

Hi,

I'm trying to use PSE 10 and Curvemeister to create .acv curves to use in QTRGui Curve Creation (load curve).
But QTR shows an error. 
'usage: qacv filename.acv curvenum>curve.out
CMtest.acv did not return valid coordinates at quadprofile.pl line ??
Curve Creation  failed'

What .acv files are accepted by QTR?

Thanks,

Frank
