GP Premium Deactivated

First of all, I'm not a developer.

I'm working on a new website for my business on my desktop using Xampp.

I've logged into WordPress and received a notification about a new version of my GP Premium. When I click to Update an error appears saying something like the new files couldn't be copied and it refers to the location of the files on my desktop.

I want to reactivate GP Premium but I'm afraid because I don't want to lose my website.

Is there anything to do?

Please, I need some help.

Thanks by the way.
