Endless problems ...nothing showing up, showing up without texture ... I resisted asking the question on the website as they don't take kindly to people who don't read the instructions.
I must say their instructions are very clear and repeated with each addon. Anyway ...long story short, while wandering thru the support forum at HJG, I spotted a one-liner buried in a thread.
"have you unchecked directx10 preview" ...jeezz
