Don't use it - it is a real b***er to uninstall (ie pretty tough, it doesn't show up in the control panel >add/remove, and the uninstall option is blocked wtf), I had to do a rollback to a previous start because a) WinMX didn't work b) when I ripped it out manually, NAV messed up, !!!??? and needed a reinstall. When I used a previous version I did actually manage to download... oh, one song. Stick with KazaaLIte - the king of P2P!!!!!!!!!!!!
