Greenfoot 2.2.0 is now officially released, and available for download (although the stand-alone USB-stick version will follow shortly). We recommend upgrading, especially for users who were on the 2.2.0 beta, as the beta version is not supported.
If you were on the beta, there is a name change to the storage API (PlayerData became UserInfo) which you'll need to change in your code when you load up your beta scenarios. I think everything apart from that name change is the same, though. If you imported the ScoreBoard class and haven't altered it, you might find it easiest to remove it and re-import the class (which has now been adjusted). Additionally, the Counter class had some bugs in the beta which have now been fixed, so you may want to re-import that one, too. Such are the perils of beta versions!
