so i think i downloaded all that i need.
in a folder i put
sbfactor.exe
sbfactor.cfg
sob.dat
results.txt
i think i changed the config file correctly, but when i try to run sbfactor.exe it pops up a dos box and then disappears right away. I get a file sbfactor.log and all the information i get is
SBFactor v1.25.5
P-1 and ECM factoring for number of the form k*2^n+1 and k*2^n-1.
