Error while running factmsieve.py
 

Hello,

I've exactly followed the instructions as described in the standalone script here [URL]http://mersenneforum.org/showpost.php?p=418345&postcount=25[/URL] about 8 months ago and I had kept functionnal my installation & compilation.

But whan I want to run it today there is an error.
