Try closing all Virtualbox windows, if you can. Then use the Windows process manager thingy to shut down any V'box processes that might be remaining (or use it to kill V'box if you can't close the windows manually). Then it might be a good idea to reboot your PC, although perhaps not essential, so don't if you have other things you want to keep running. And then try Vagrant again, but this time keep your fingers crossed in the appropriate manner. :)
