That is because you no longer need Enhanced anything, it is replaced by Experience add-on which you should have access to as a Premier subscriber.
Log into your account, and under the WordPress Products you should see Downloads, Click on that and download EXP.
Once you have downloaded it get rid of , deactivate and delete those old Legacy (enhanced , etc) add-ons.
Sorry for any confusion. Here is some info about Premier subscription and where to enter idi f you are having difficulty accessing.
I am reviewing the premier changelog, the developer just updated how the renewals and auto updater works so it may look different on your screen then it does for me, but you should be able to access all the downloads. , I noted in your account you had already downloaded Power to replace Propack and tagalong
Let me know if you have any issues or questions after accessing .
You will want to review the documentation site since verbiage may have changed. You will also see a lot of additional features with Premier.
