Well, that didn't work.
Now I'm lost!
factmsieve.py wouldn't restart - kept giving an error 255. Renamed number.dat.cyc and that cleared the factmsieve.py error. But, number.dat was trashed. Rebuilt that, but factmsieve.py wouldn't go anywhere, so I have moved to msieve direct entry. Now all I get are -11 errors for the entire 4G number.dat file. Currently, I'm retrieving the rels from the spairs.save.gz file to see if I can get anywhere from there.
