The error message:
UseProductKey failed: failed to send HTTP request.
This is caused by NovaTuneUp not being able to find an active Internet connection.
To solve the problem proceed as follows:
- Open this Internet page: http://www.novastor.com
Once the page has loaded activate the license key while keeping the Internet page open.
If this does not solve the problem, you must have blockedNovaTuneUp in your firewall.
You will have to configure your firewall to allow NovaTuneUp to communicate through it.
