FINALLY WORKS!!
*edit* to make it very clear **************
Copy sspl manual to device & run it (from your phone with file explorer or Total commander), it'll force your phone into multicolored screen, once in multicolored screen run the .37.exe file on your PC & it should work!
*****************

Here's what I did.
Took out SD card, rebooted 30 times, threw a stick over my left shoulder, took a dump, drank a 6 pack... (ha! and it still didn't work)

So, I went with this note in post 1:
NOTE 2: anyone having problems with the device entering SSPL automatically, please copy SSPLManual.exe from the SSPLManual.zip attachment to the device and run it. then once the screen is in SSPL, run RUU manually. i.e. you run the RUU on the PC, if it isn't obvious.

*Don't worry about the RUU part, it expands when you run the .37 exe file (and it worked with a Sprint .4 ROM).

HAPPY!~

*edit*
Off course I didn't think 'I' needed to run the ssplmanual from the device! After all.... I know a few tricks... like vol down & off button at same time while resetting with stylus...

HA! Key generated spl screen DIDN"T WORK, but ssplmanual from device DID. And that's all I can say about that!
