I wanted to first install the game under Windows 7, since a previous speaker has already written, it would work. When downloading and installing there were no problems and the product key was apparently also accepted. After I opened the program, however, the error message that you, etc. need to open the game Windows XP, 2000 came. So I tried it in Windows XP, also has everything works and the key was accepted for a second time during the installation, only when I opened the game again, me the game client asked the software with the Key to Enable. If I get the Amazon keys now but text box that tells me the client that Key "entered incorrectly or formal error" was. This can guarantee is not the case, so I added it by copying and pasting 1 to 1 from Amazon
If I were to rate the game here, I would certainly give 5 star (as I have previously played times years ago and am still errinere that it was pretty good), but if I can not even play the game, then remains for me nothing choice but to evaluate bad ...
