Upgraded Dash does not recognize me

I paid for full membership, but when I try to add DASH to my site it does not recognize me. Says I am somebody else and click to UPGRADE. Then I click, and then it knows who I am and I download, uninstall old dash, upload new dash and NOPE, it still thinks I am somebody else and says I have to upgrade. I signed up for a full year thinking I could use your services on several sites. Now it does not even work on the site I was using when I made the purchase. Somehow it has an old/different ID For me from long ago and it not recognizing me as an Elite customer. I am Dewey
