Hey Guys,
I had this same problem, Calkewalk tracks cut off at the end, and there was a guy named James on this Forum who said to try this: (In Cakewalk) Go to Edit, Preferences, Configuration File, ( You have to be in the advanced setting to see these options). Then reset Config to Default, then reset Config files, everything works perfectly after that. I take no credit but wanted to thank James, I would never have figured this out myself.
