Believe it or not, I have 1.2.1, but I use 1.3.1. Once I opened the folder for 1.2.1 and I got 1.2.1 by accident. Then I wanted to go back to 1.3.1. I relized I did not have the patch for soldat 1.2.1 to 1.3. OMG!!! I was going insane. If I downloaded 1.3.1 again it would take 3 hours and my internet disconnects by itself every 2 hours ( I dont know why ). It took me hours to find the patch for 1.2.1 to 1.3 I found it. So I went from 1.2.1 to 1.3 and then from 1.3 to 1.3.1 because I had the patch for 1.3 to 1.3.1. If you understand what I am saying, then you are really smart
