CORE Virtual box Issues

I am trying to run a virual instlation of CORE on ubuntu: link-

However I am having issues with virtual box that I do not know how to resolve.

The errors are as follows.


Any help would be briliant!

Have you restarted your PC since installing VirtualBox? On Linux VBox adds new kernel modules that need to be loaded, which requires a restart.

Yes I am afraid so.

Virtual box has been installed for some time and I have just restarted after this issue.
