I've downloaded TAILS and when I boot everything goes normally until it fully boots up, at which point it shows the desktop for a second and then says Uh Oh! An error has occured or something similar.I've tried going to the other consoles withCtrl+Alt+F4 and all of them ask for a username and password which I can't find after looking up and was never asked to enter. I'm using VirtualBox on Windows 10.
