Installation Issues

[The Outsider]

Hey guys, I wanted to start a thread for those who encounter problems while trying to install the game. This way, we might be able to give some advice. So now, let me be the first example in this manner. :D I was on vacation in uk and bought me collectors edition copy of Rome 2. I came back to Cyprus yerterday and as you would imagine tried to install my game. But no. After entering the steam application code the game tells me that it is not available to purchase in my region. What the hell? I have bought all my previous total war games including empire and shogun 2, from uk and played them in Cyprus. Hell I have even ordered steam supported pc games from the states and they work fine so what the ***** is wrong with this one? Any advice would be greatly appricieted.
