2x plugin / 2 websites – mix up

Hello,
I have just purchased 2x Curcy Multi Currency plugin (I had used it in the past but it has expired).
I use it on the following 2 websites:
https://thai-clothing.com
https://moleculepants.com

I managed to make it work on the second (molecule… key: 169a********************2dd240dc) but on the first (thai-clothing key: 1b109********************cbe02c0) it says: “…Key is being verified. You can check Auto Update…” but it doesn’t work!
On the Villatheme download page it shows: “active on: moleculepants.com” which obviously is incorrect, it need to be active on thai-cloting.com!
How can I change it?
On Envato manage your apps, there is only 1 revoke access button and I don’t know which one it will revoke. Shouldn’t theere be 2 buttons?
I hope you can help asap,
Thank you very much,
Su
