Vista Sucks

I just bought a new computer. The old one is just way too slow and there's no enough room to store all my porn haha. The problem is that the computer came with Vista Home Premium. A lot of programs just aren't compatible with Vista. I finally figured out a way to make Quickbooks 2007 to work. In the process of installing some old software, I somehow screwed up Vista or Vista screwed me up. When I turned on the computer, it won't go into Window and it kept going back to the blue screen. I had to return it to the shop and have them installed it again for me. It's finally working alright I think. I figured out how to set up a network. It's pretty functional right now except a few glitches. But I still don't know how to make my Civilization IV game to work on Vista. If anyone knows, let me know.
