NIS Will not update

For 3 days now the NIS 2011 will not update

 

I get a message saying my computer needs my attention urgently.  I have tried to update manually

 

I verified I had plenty of disk space

 

closed all applications

 

nothing worked

 

I clicked on the Fix Now and it said it found no issues, but still it will not update

 

 

When I click on the Support button, it asks me to upgrade to 2012 ... I still have 100 days left on my 2011 subscription, so happens if I upgrade?  do I have 100 days of 2012 or do I lose that?

 

I got a message window saying it found a new error.. I have tried to attach it here in Open Office Write format  but it was not accepted ... so basically, in the One Click Support window, I get a message saying"We Have Encountered a new error with Norton Internet Security    Error: 8920,208"
