I used the trial version of uSync complete, and thought it was pretty convenient. So we decided to buy the licence.

I tried adding the licence to our Test environment, but I needed to update the version, so I tried it with the package update in Umbraco. The uSync version was updated, but the licence did not work, I get the notification: 'Your licence is valid. Your licence is invalid' in a red banner, on the licence tab. On all other tabs it's just 'Your licence is invalid'

So I decided to update the nuget packages of my project on the development environment. and after that the licence works. But when I deploy it to my test environment, I get the same notification as before. Even after removing the entire site before deploying.
