Hi Jim, (It's Brendon, not Brandon)
We still haven't solved why your learning center PDFs aren't downloading and appearing properly, and you still haven't told me if you can download and display them from my links, above. (Other people tell me they can use the above links, so we're trying to solve whatever is interfering in your machine)
Do the PDFs download from the Learning Center screen?
Do they download from my links?
You seem to have some 'file association' problems if they sometimes start Edge and appear in there instead of Foxit, or are we mis-communicating? In either case, I'm keen to keep going and help you with these problems. Please answer those two questions above.
Finally, you seem to be indicating that you have both NXT4 and Creator 2012 installed on your machine. I think that might cause a tangle, but since NXT4 can only be installed a limited number of times I'm not game to waste an install by trying to install them both on one machine, just to see if there's a tangle. :) However if there are any PDFs you can see, that you want but can't get, please let me know and I'll try to get them for you.
