No, what you need is to purchase it. This is the wrong place to be seeking a crack. Anyone caught passing out cracks, serials, reg. keys, etc., to commercial programs will be permanently banned.

Charon is a better program anyway, and it's free. You can find a link to it in this section. The latest version is v0.6, but v0.5.4.1 could be faster for you unless the new Blacklist Scanner is needed.

I purchased it. very nice program! 8)
