Thanks for the try, Jewelsy. Still getting the error message... It comes just after I hit the I Accept button, which (based on some late-night Googling) I do believe is supposed to then ask me to review some disclosures and then provide my receipt and the download options. It's bizarro! I may just have to give up, at this point.
Thanks again to you and MFWalkoff* for trying to help. I appreciate it!
