BF1&5 problems starting

Hi! I have BF1 and BF5, and whenever I try to play, the following message keeps appearing: Please update your AMD Radeon driver. AMD Radeon driver version 0.0.0 was detected. The required driver version is 16.20.1025 or later. Please update your drivers at http://www.amd.com/ before playing. I pressed "OK" or "X," but the game won't start! I have driver version 26.6.4. What should I do? Thank you!
