yeah that's the latest rev. if the other wads are working and that's the only one giving you problems, you could try uninstalling and re-installing that wad. if still nothing, try downloading it again and then repeat the above steps just to see if you caught a bad download.
also, i know you checked, but check one more time to make sure that the spelling is correct on the /apps/wadmanager/boot.dol folder on your card, and that it's all lowercase just for if it might be case sensitive.
i gotta take off in a few but hope you get it working.

if it helps,i get the now loading,but then it freezes right where wad manager should boot
