I tried what you said in an earlier post, Mortlach, but it still doesn't list any of my addons (no version numbers in the Installed column). I did finally update some addons (AutoBar, Cartographer, FuBar, Talented and the DewDrop Library) by hand. That's fixed most of my problems with MazzleUI, but I still haven't quite figured how to get the Talented addon working. It shows that my Lvl 30 Hunter is only Lvl 29, and I apparently have lost the point for Lvl 30 - but I'm still working on it! (If you have any suggestions for that I would be very grateful)! Otherwise, any further assistance with MacAceUpdater would also be gratefully received!
PS I know that helping a noob like me can be a real pain in the *** as well as a waste of valuable playing time, so I can only repeat that I really appreciate what you've done for me so far.
