YAY! I got it to work!
However, I have a leeeetle question:
In the Help, it says that the 3rd forward characteristics box is for the difference between the first two measurements (I think...there's also something in there about difference between "ideal" and "measured")...
...but when I entered the differences in voltage and current between my first 2 measurements into the 3rd box, it simply errorred (microsoft doesn't think "errorred" is a word, but I disagree)...
...when I entered values into box 3 from much higher up on the Id vs Vf graph, it did not error.
So, presumably, the 3rd box is for values much higher up on the graph. ???????
BTW, I tried values for the 3rd box that were higher, but only moderately higher than the "knee" value, and the program wouldn't accept them. It wasn't until I took values much higher up, well into the saturated portion of the graph, that the program accepted them.
FINALLY, my simulation is now happy...thank God. And thank Hendrik Van Zwerver.

For anyone who might care (doubtful), here's what I ended up with for the Kingbright WP710A10SRC (660 nm 3 mm T1) LED:
.model WP710A10SRC d(
+ IS=4.58E-13 N=2.973 RS=1.197388
+ EG=1.43 XTI=3)
