It has come to our attention that some PS4 uses can't start PS4 PSN games downloaded from the store. Our forum member Doddy884 had this problem and thankfully found a fix. (thanks Doddy)
If you get this message when trying to start a game:
"Your ps4 is not connected to the internet cannot verify the licence"
You firstly need to restart your router then your PS4. Go to settings> PSN>restore licenses.
The games that were effected were Warframe and Resogun.
