You have version 2.0.9 installed. Update to 2.1.2.
Compatibility with WordPress 3.0: 100% (according to its author)
Hit update -> Automated WordPress update has failed to complete
However, if I manually download it from both this site and the Authors site, it only installs 2.0.9.
Om adifferent matter, I also marked this as "broke" and for some weird reason it added "1" to "people say it works". Just to confirm im not mad, my friend logged in and marked it as "broke" (after about 2-3 min of confirming the mouse was over the BROKE button) and it then added "2" to "people say it works"!?!?!
