I've had CS:GO for nearly 1 month. My experience has been decent, but not good by any stretch. It started when I went into my first comp game. I did pretty decently and ended up at the top of my team (we got battered 0:16) but I didn't get anything. Then in my 5th or 6th game, I got a 7 day ban because I was paired with a clan and they instantly kicked me. Soon after getting back from that ban, I played brilliantly (I had still played casual, death match and arms race) but my team couldn't do anything. They walked and fired all over the place. We ended up getting beaten. This reoccurred again and again and again. Just today I finally managed to get on with my friends (which was a challenge because my internet has been messing up, see my post in ADSL) and I got my 10th comp victory and was put into silver 1. I felt really ripped off because I was always put with much worse players and was kicked my a clan. Anyway, I started playing a comp match just a few mins ago and I got the "... Does not match server files." Error. I went through the procedures needed and then went back on the game. When I get back on, boom. 7day ban. I finally get to play unlimited comp games and now I'm banned for an error in the game or with my parents computer (My other PCs are in the process of being built.) What makes this worse is that I cannot appeal against this. Now I have to go back to stupid casual. It's not like I've hacked the game or anything but I feel like I'm being treated like a member of lizard squad. Gosh darn you Gabe....
