Sshhhhh - don't tell anybody: we had nasty (and quite common) bugs in our hash-creator: while it worked well with "usual" strings, some hashes didn't work, especially those with a ', " or \. Since nobody complained, they might have gone completely unnoticed.
They are fixed now, only the ntlm-/lm-hashes weren't completely fixable: strings with both ' and " will give an empty hash and an error-message now. I'll try to fix this issue during the next week as well.
Mapping the Net crossed 3 Million Domains, but is running out of Disk-Space. The new server is here and will replace the old one by the end of March.
