How to update iWork if it is showing you have to purchase again

OK I was having trouble with with 2011 Mac Mini and iWork I bought on DVD & the preinstalled iWork not updating.

Here's how I got it to update in through the app store.

Open App Store on your Mac if they don't show as an update in the tab and are not in your Purchases tab, go to the Featured tab & click Account under Quick Links, enter your password, & click Reset all warning for buying and downloading at the bottom of this page, & click Done.

Check your updates tab & iWork & iLife updates should now appear, at least this is how I got it to work on my 2011 Mac Mini.
