Have successfully updated my Kagu by downloading latest version (1.0.10.2) without a problem. However, have found very curious (but readily reparable, I assume) feature which I'm certain other users also will be quick to notice and point out:

Album title listings identify and label, in addition to the names of the albums, the number of tracks on each album -- but calling them "songs." It might, perhaps, be slightly useful to some users to give the number of tracks on each album, but not to label them as "songs" (even if they sometimes are). In my case, they're usually movements in classical compositions or chapters in books.

Anyway, again my appreciation to all responsible for the hard work and constant improvements in this already splendid and most useful application.
