I was having issues with Shareaza 2.5.1.0 (see Note if you give a hoot). I uninstalled 2.5.1.0 then went back to 2.5.0.0. I tried to import the eDonkey partials, failure. I waited until after my 50GB library was rehashed, hoping it would auto recover the partials, I'm a bigger douche than I thought. Started a new download, still no dice.
Dazzle Me Baby.

Note: It would not connect to the G2 Network (kept trying Asian Hubs, and kept being denied) and search results were moving randomly (even after clicking Stop) when I would try to highlight them (very distracting). NOW I know how to empty the host cache but rolled back to 2.5.0 before I read the forums (assuming it was just the new version experiencing bugs).
