Which Chartboost SDK version to use?

[Outcast]

I wonder what SDK version of Chartboost I should use when building my game in xcode? When I add an older version I can build, but when I add the latest Chartboost SDK 6.5.2 I get a build error.
Do the object need to be updated before we can use latest SDK:s or should you always be able to use any SDK as they are released?

I saw the other thread, seems like I needed to add the Security framework for it to work!

Is very difficult to know what could be happening if you don't show a log from iOS, sure you add all external libs?
