That is all OK. You need to play on updated servers. That's what an update means.i downloaded the orange box version right from the setti page and every game i join says that i cant join because im using a newer version and theyre using the older version
There are still lots of not updated servers (v34). The current new version is v45. Check server game versions here: http://css.setti.info/servers/css/
