Game is brand new but says disc is dirty same with other ea games

Brought GW2 2 weeks ago , loved the game , brought a coin bundle in DLC , after that the game won't load says . Plz check if the disc is dirty, broken or is upside down , if it wasn't doing the same with Star Wars battlefront , both games are PS4 , FIFA 16 works fine , what's going on , all my discs are in mint condition, every other game I own is fine aswell , I can't even take the risk by selling on eBay - it's a joke
