Digital BW, The Print

I've been doing a search of past posts on the board, so please forgive me if I missed something.

What I read seemed to indicate that if you use QTR to create RGB (vs grayscale) profiles Lightroom would work with them.  

Over the past few years I have only used the create ICC RGB feature to linearize my UTR2 inkset on a R220, but when I try to print with them Lightroom gives me the following error: "the custom profile selected for this print job is missing or invalid.  If you continue this print job the colors will not be managed by Lightroom."

The profiles work fine in PS 7 and CS3.

Are there any workarounds for this?
