Subscription

1.)  I had 4 computers, all with NAV installed.  Now have only 3.

 

2.)  Current subscription status:

 

          a)  subscrption for 3 computers     -     3 installed, 0 available     -     Expiration:  Mar. 14, 2011

                     ( 2 installed on current computers  -  NAV10 automatically upgraded to 11)

 

          b)  subscription for 3 computers     -     1 installed, 2 available     -     Expiration:  Jan. 03, 2012

                     ( 1 installed on current computer    -  NAV11)

 

3.)  My question:  How do I install available 2 subscriptions on 2 computers whose subscriptions are expiring?

( I have tried uninstalling and then reinstalling, but with no effect on expiration date.).

 

Thanks
