Unable to upgrade existing plugins after updating account

Hello, I was a member back in 2011 and have been using some plugins since then that really need to be updated. I got a one year membership through AppSumo which I have just activated but when I login to my Wordpress site it still says "Upgrade to Update" - my account is already upgraded but some reason it seems to think my account is cancelled. Can you please check and advise how to get this resolved so I can update my plugins? Thanks!
