NIS2013 problems

I have installed NIS2013 and had the subscriptions correected, BUT NIS2103 is a pain! How do I reinstall NIS2012 and reset the subscriptions? Will I have to recreate the login entries?

 

I am finding that everytime I start up IE9 I have to click on Login Assistant which brings up two screens. I log into my Norton account which appears to be accepted but always comes back with a network failure message, but the second screen is activated and I can enter my vault password.  However, entries in the vault have been re-arranged into different categories including Government and Technology which I can empty, but not delete.

 

Are there any suggestions that might help or should I go back to NIS2012?
