Besides installing BOINC and VirtualBox, what do I need to do to complete a task for Test4Theory? Do I need to create the virtual machine or does the project supply that? Do I have to have VirtualBox started before downloading tasks, or does the wrapper do that?

So far, I've only gotten 20 second computation errors. I'm assuming there's something I'm failing to do. This smells like a configuration problem. What am I missing?
