Failed to open a session for the virtual machine Windows.

I hesitate to say as I don't know why you would have changed it in the first place. VitrualBox (due to security) must be run from a folder that is owned by root. Something that you have installed or you manually changed it to be world writeable (everyone can write to it). Changing it back to root:root using chown (as su) will probably fix it but what ever the reason that it was changed to begin with will probably not work any more.

I did not change permissions of any folder, so this can't be the problem... something else must be.
edit I meant the world writable error.
The error can only happen the directory where VirtualBox is installed is not owned by root. What is the host?
