Proth appears to cap k at 2^31, and when I run LLR on the output file from NewPGen, it only spits back the first line of the input file. What am I doing wrong?

Separate question: I remembered reading something about it being faster to just LLR small n's, rather than sieving them; I pulled the small n out of the sieve, then restarted it. It appears to have restarted sieving at p=2, even though the top line of the file showed p=2 billion (roughly) at last save. Is there some paramater to alter when you pull part of a sieve file to prevent it starting over?

Finally, can I force LLR to test primality (PRP, I think, since k>2^n) for the really small cases of n? Say, less than 1500. I tried Proth for this, discovering the apparent 2^31 limit.

Am I just better off picking a k smaller than 2^31 and restarting?
