*Script Alert* No sale belonging to the current user found with that code

I just purchased a new script for Adobe Photoshop named Plexus Maker Photoshop Extension and when I try to enter the Item Purchase Code this message pops up:

Script Alert

No sale belonging to the current user found with that code

Hi

for solving purchase code or item license issue will need to get support from the item author. They (author) are the right team to help. you can contact item author through item comments page or author profile page or best option is through item support page.

How to contact an author to get support or for any technical query:

Thanks
