Long story short upgraded laptops. Moved library over to new machine. Running Snow Leopard at the moment. 2.6 seems to be running okay on this new machine.

However my X1 and it's custom mapping don't seem to function as nicely with this version of Traktor. The beat nudge buttons take forever to beat match, where as before my phase meter was much closer and only required a few clicks left or right on the X1. Now my tracks are all over the place and require a hefty amount of button mashing to beat match the tracks and align them correctly.
Anyone know of a way I can revert to 2.5.1? I still have it installed on my old machine.
