I have played 1600+ hours of GCIII. But since the last update can no longer launch GCIII. I have uninstalled, reinstalled, cleared down load caches, run as administrator, When I verify I am told one file needs to be reacquired, then nothing. It does not reacquire. All I get now is the Start Menu then nothing, very frustrating. (I have been running Windows 10 for years).
