VirtualBox runs as root, Critical Error as user

Question

I've just done a fresh install of VirtualBox 4.3.10 on a relatively fresh install of 14.04 (Trusty) and am seeing the below error when attempting to start VB as a normal user

Failed to create the VirtualBox COM object.
The application will now terminate.
Callee RC: NS_BASE_STREAM_WOULD_BLOCK (0x80470007)

When I start as root, it appears to be working just fine. So, I'm guessing this is a permissions thing, but I don't know where to start as far as figuring out what exactly has the wrong permissions.

I've actually tried several different installation methods including the .deb's from oracle's website, Ubuntu Software Center, and via 'sudo apt-get install virtualbox'. I get the same result regardless of installation method.

Any ideas?

Solution

Deleting ~/.config/VirtualBox should solve your problem.

Delete is using rm -r ~/.config/VirtualBox and start you virtual box. `
