I have installed Backtrack 5 R3 64-bit using Virtualbox. Now I am attempting to install the Virtual Guest Addon using the following command:

root@bt:~# wget http://download.virtualbox.org/virtu...ions_4.0.8.iso

I attempted 3 times already, but the screen goes completely black at about 20% completion. All of the lines of text along with the completion rate disappear. I tried restarting my computer, but the same problem keeps occurring.

Is there a way to remedy this issue? I tried looking on the forums and google, but I couldn't find anything in particular solution to this problem. Any help would be appreciated. Thanks.
