I recently downloaded 2012-05-04 - krpano 1.0.8.15 - PreRelease 2 (Viewer only)
Updated a existing Tour and ended up getting a blank screen not loading the first scene.
I figured out that the soundplugin might be the troublemaker. Taking the one (soundplugin.swf) from the previous PreRelease fixed the problem.
Can anyone confirm this?
Greetings
