this is a Linux 3.12-kali-amd64
Debian GNU/Linux Kali 1.0.7

• After the install, I create a user and add that user to admin group

• Then I made the Clean, Update, Upgrade and dist-upgrade

• After that, the first time I tried to install and it crashed, then I re install the system, I made all the same things, but in that case, I tried to install firefox and It crashed again, after that 2nd time I re install fir 3rd time and, after the installation I tried to install a print driver and crash Again.

• after all the 3 thgns I look the same behavior, it remove the Network icon (at the right-up corner) and in the module Applications>Internet disapired the Desktop Sharing Icon and the Iceweasel Icon.

• When I restart the system there apeared a message after the loggin:
  "the programs included with the kali gnu/linux systems are free software;
  the exact distribution terms for each program are decribed in the
  individual files in /usr/share/doc/*/copyright.

kali gnu/linux comes with absolutely no warranty, to the extent permitted by applicable law".

• Then it looks like there is just a line command SO and I can't enter to the system, I made ifconfig and some command and it response,when I put ifconfig, the wlan0 and the Eth0 are disable.
