What I would recommend people to do in order to keep stress levels down:
1) Update your graphics card drivers. Download an install the driver then restart your pc.
2) Update DirectX here: http://www.microsoft.com/downloads/e...D-85FC422D1388
Select ďDirectX End-User RuntimeĒ download the file and run. Then let Microsoft do itís thing.
3) Register and install Steam here: http://store.steampowered.com/
Once Steam has done itís thing and updated, it may start up in a big browser type window. Personally I find this annoying. To stop this appearing go to: View > Small Mode.
4) Now I would install Civ V, either by means of your DVD or digital download.
If you need any help then just ask me, Iíll be happy to. If you get stressed, have a cuppa. Games are not like they use to be, and I have a feeling this will become the norm.
