ChildhoodOBCD (DayZ)

Well here I'm having the same issue. Here's my story: Played with DayZ Commander up until today. Upgraded DayZ through Commander yesterday. Played on one server for most of the day. Then today I heard something about how launching from 3rd party software rewrites your CFG file and I'm having some FPS issues so I wanted to test that out. The same server than I was playing on not 12 hours ago now says Required: 1.62.101480 If this is a DayZ version thing, then why can't I join a server that I know for a fact is running DayZ 1.7.5.1 Does DayZ Commander have some evil plan to hide updated versions so that you have to use it?
