Opening Virtual Kiosk

When I right click on the Comodo icon and open, then click on virtual kiosk, a black box opens up and says loading. That’s all id does, nothing loads and no way to X out and close. Why doesn’t this open the kiosk? Had it opened the other day with no problem?

Hi Eastway,
Try resetting the sandbox and try again, thanks.
