Whonix won't start.

I have installed VirtualBox and the Whonix XFCE and imported it into VirtualBox. When starting both the Gateway and Workstation, they don’t start and it says “Incomplete mode parameter data”.

Stays stuck there forever?

Please see and answer these: Kicksecure ™ in VirtualBox - Troubleshooting - Kicksecure ™ does not Start?
