Mike,

Capital letters don't work here.  Use .txt and .quad not .TXT and .QUAD

They don't provide .qidf files so you've got to start from scratch as

I'd recommend using custom ICC profiles rather than redoing the QTR (.quad)
profiles.  This is a lot easier and you get better screen-to-print matching and
softproofing as well.
