If you're using Windows 10 or you've been installing Windows Updates on Windows Vista, 7, or 8, you may find that games using SecuROM or SafeDisc will not work! LEGO Racers, LEGO Rock Raiders and LEGO Drome Racers all use SafeDisc. There may be other LEGO games affected. If you are affected and aren't running Windows 10, the information in some of the links below should help. http://hexus.net/tech/news/software/86720-safedisc-securom-drm-support-removed-windows-8-7-vista/ http://www.geek.com/
