NIS 2013 - Installed and wont start....does nothing at all!

Just installed NIS 2013 for the umpteenth time and it wont start up.  Loads ok, downloads the updates, says its initialising and then says 'Installed' reboot your computer to start up.  Upon doing so, it never does start...even when I click the icon or use the norton tab from program files...nothing.  I have uninstalled using the removal tool, but that did a very bad job of removing everything, so I did it myself including removing the entries from the registry. My previous version, NIS 2012 was fine, but this thing is useless!  It also knocks out communication with the internet as well.  Cant see why that happens - no browser can work, no response to pings either.  I usually have to restore back with a system restore before I start all over again.

 

Im using Windows Vista home premium, SP2 32 bit.

 

Can anyone help me?
