I am using Oracle Virtual Box version 4.2.16 r86992. Everything was fine until yesterday shutdown. Today, it shows inaccessible and throws this error:

Answer 1

VirtualBox 4.3 is released and could it be that you've updated or there was some issues while updating?

In any case if you are not able to bring up the Virtualbox, remember to backup the VirutalBox VMs folder and going for a fresh install should be the best way forward.
