Hmm, I specifically tested that case. Could you check C:\Users\<user>\AppData\Roaming\XBMC\addons\script.moviesetart (I assume Windows?) has actually been updated? I have noticed install from zip doesn't always seem to work on upgrade. Perhaps blow that folder away and install again.

If you still have trouble, feel free to enable debugging and send me the log. You should see something like...
