Failed to load GUI ... Callee RC: ERROR_NON_MAPPED

[x000111]

This morning I came into work and was going to start up my VM and start getting things done. But instead, I got the error, quoted below, when I attempted to open VirtualBox. I've done some searching and cannot find anything out there with this specific error message. Maybe I'm blind or this is just something obvious and I haven't had my coffee yet. Nonetheless, does anyone out there know what would be causing this or if there is a fix?

More details...
When I double click the VirtualBox desktop icon or open it through the start menu, I get the error message below. The VirtualBox window does not appear at all. Instead, this error instantly pops up. I am on a work computer that other people use at times. So any number of things can happened to this computer while I am not here. I'm running Windows 7.

Failed to load the global GUI configuration from .

The application will now terminate.

Well, after restarting two times (no updates were installed) VirtualBox is working again. Wish I knew the exact cause.
