I installed astrometry.net locally and to test it I set up a new sequence. Under target settings, I pointed to an image I have on my hard drive for “reference data” and hit blind solve. SGP then gives a plate solve error saying “No reference image selected”. I tried it with jpg, tif and cr2 files. Maybe I’m just doing something wrong because I usually use the framing and mosaic wizard and haven’t done it this way in a while.
