You should direct any queries regarding your license to [email protected]
, but basically, when your license is installed that's it.
You don't say whether you are licensed through Steam or via the traditional key-file.

C2 is totally backward compatible. I can open (plugin dependent) any previous C2 program with the latest build.zenox982013-08-02 22:24:52
