Horton Sandbox wont start

[Kevintra]

Newbie to Virtual box and Horton Sandbox
It was working great for a month than all of sudden top working. Friend suggested may be corrupted so do an import reinstall.

Now everytime I can start it but it is stuck at "Starting Sandbox Container" and freezes my pc.
All the other virtual machine are working fine except horton sandbox .
I have uploaded virtual box hardening log as suggested.
