I was finishing a project and generating outputs previews and checking while changing some links of the social network icons. I don't know what I could alter, but suddenly if I try to preview the browser is black. However, if I preview with other skin.ggsk the tour is visible.
In the Pano2vr work interface is everything ok, menu, icons, navigation, buttons ..... nothing has changed. What could have happened ?
Help would be greatly appreciated. The project was completed and ready to be delivered to my client shortly.

Many thanks,
Javier
