Hi.
When I click to open City Car Driving, it says: do you want to allow the following program from an unknown publisher to make changes to this computer? Then, i see a loading cursor symbol, and then it just stops and nothing happens. Feel like ive been ripped off of 25$

You should run the game with administrator privileges (right click on its' shortcut and choose "Run as administrator" in the context menu). Then enter your activation key again.
If launching as administrator didn't work, then follow these steps:
1. Disable the UAC. Detailed instruction how to do it –

2. Temporary turn off any antivirus or firewall software.
3. Run the game with administrator privileges again (right click on it and choose "Run as administrator" in the context menu).
