Well the good news (that I got it to load) didn't last.
It doesn't work.....
That is, I cannot add ANY lots to the menu. They show up, pop up an error box (no matter what lot out of thousands I select) that says "Unknown format of the preview image (not PNG or JPG) with TGI:"... and so all the previews are blank..
I figured, okay no previews... that's bad enough.
But then, when I select the lot (it turns blue in the UI and the "Selected" count goes up), and hit "Add".... nothing happens. Absolutely nothing, except the UI flickers a bit. It doesn't add to the menu, doesn't give an error, nothing....
