Problems occur while running Virtual Box

Hi all,
A little help if you can. I am running Virtual Box and problems are occurring. Screenshot of error is given below:
Virtualbox-dkms package is installed on my computer. Sudo modprobe vboxdrv appeared stating that vboxdrv is NOT installed so I installed the package again but the same error occurs.
I then took out virtualbox and installed it again as well as the packages that come with it, but the same error appears.
Can anybody give me straight to the point, easy to follow instructions on how to fix this (I'm not very technical).
Thanks in advance.
