If i buy a new game from Steam will it Work?

Is it possible that you get my activation key and cancel it and send me a activation key i can use on steam instead?

Hi Thank you for he answer. I have bought the game direct from http://www.cycling-manager.com But here on Windows 8,1 i cant even run the exe files. So i uninstalled the game but i cant install the game Again. Windwos 8.1 cant run the .exe file from cyanid/focus? not as administrator and not set in ...

Hi

Just updated my computer to Windows 8,1 but now the game dosen´t Work anymore.

Its not possible to downgrade to WIndows 8,0 Again.
What can i do so the game will Work Again?
