I have download all the discs onto my Windows 8.1 laptop for the Star Wars Battlefront Ultimate edition game, but get an error message when I try to open it to play. The message says 'Please update your AMD Radeon Driver. Detected AMD Radeon driver version 13.251. The required driver version is 15.7 or later'. However when I log on the AMD website I can't find a version 15.7 or later to download. Any guidance on which version of AMD driver I should download from the website to enable me to play the game would be very much appreciated (there are so many to choose from!)? Thanks.
