Importing transistor spice model to LTSpice not working
I don't think you can add a + to indicate a line extension, its 1 line per model. It should look like the others. Here is an example:

.model RFNL5BM6S D(Is=778.9p N=1.419 Rs=25.53m Ikf=81.74m Eg=1.05 Cjo=93p M=513.2m Vj=714.8m Isr=358.2p Nr=3 Bv=600 tt=88.29n Tikf=18m Trs1=700u Iave=5 Vpk=600 mfg=Rohm type=FastRecovery)


Second thing, check your directory. The new LT spice places a folder in

 User\Documents\LTspiceXVII\lib\cmp\standard.dio


this is the one that needs to be edited.
