Hello there, I think I've found a fix for football manager with 6.0.3 patch and maybe older patches.
Football manager use SafeDisc driver installed on your computer. I think if we disable the access to safedisc driver, the game maybe will start.
The key is located in the registry under:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Secdrv
Right click on folder and deny all to access this services.
Maybe this is a solution but I didnt test it yet.
