Please read the following: Minimum information needed for assistance. Specifically for the VM log file ("VBox.log.zip"), here's what you do:

1. Start the VM. Not from a saved or paused state. Clean start.
2. Take the steps required to generate/observe the error. Record the error message. EXACTLY. Post a screenshot, if you have to.
3. Shut down the VM (if it hasn't aborted by itself). Not saved, not paused. Complete shut down. If you can't shut it down by normal means, close the VM window and select "Power off".
4. Right-click on the VM in the VirtualBox Manager. Select "Show Log..."
5. Save it (just the first log), ZIP it and attach it in your response (see the "Upload attachment" at the bottom of the form).

So there are no logs from steps 4 and 5? Even after you kill VirtualBox?
