Ubuntu Networking :: "NetworkManager Is Not Running..." And Can't Restart It?

Approximately two days ago my nm-applet changed from the up & down arrows to a wireless graphic with a red exclamation point. I lost my network connection. I was playing a video game at the time. I did not install any applications, change the network settings, have any non-included crons executing, run update-manager manually, or reboot my machine within the past 24 hours of this happening.I completely removed network-manager & gnome-network-manager via Synaptic, configured my /etc/network/interfaces file properly, and rebooted. I have my network connection working via the interfaces file.

Then, I found every file I could that mentioned "NetworkManager" and deleted them.I re-installed network-manager and rebooted.e deleted files were re-created upon rebootMy network connection was working because of the /etc/network/interfaces etworkManager was not and nm-applet was showing the wireless icon with the red exclamation point.I have been trying to figure out what happened to NetworkManager. When I click on nm-applet, it says "NetworkManager is not running..." I tried to restart network-manager with the following commands and their respective errors:

Code:
xk@localhost:~$ sudo stop network-manager
stop: Unknown instance:
