Cool, the proper version should be available now. The autoupdater should work - if it doesn't you'll need to manually download the update. The autoupdater will start automatically when you run Cricket.exe (if an update is available).
For UDRS - when the ball hits the pad or the bowler thinks the batsman has snicked it, an appeal meter will appear (read: should appear). Press I to appeal when this happens and you'll review the decision.
