It's difficult, because if the error contains a message about licensing, then this must be a specific error about your permission to use it. And that means only the game developers can help you.
However, there are things you can try.
1] Check your DirectX.
If the game uses DirectX you can check for errors in DirectX on your machine by going to Start > Run, type in "dxdiag.exe", (without the quotes), and click OK. The DirectX utility will appear and this will allow you to test whether any components are not working.
2] If that doesn't work, you could try uninstalling the game and then re-installing. But with that you will probably have to reboot the computer after the uninstall, manually remove any folder and file remnants, then run a competent registry cleaner to make sure the registry doesn't still hold any entries for the game. Then reboot again, re-run the registry cleaner, reboot, and only then try to re-install the game.
But I consider that a last resort, because so often these games place files and registry entries hidden away on a computer to check for licensing issues, to avoid just such attempts to circumvent built in restrictions.
