Are you using the Program Track mode, or Programming on the Main (POM)?   You cannot read a CV in POM mode.

Unless you must know the value of a particular CV, I just ignore the 'Cannot Read CV' message and continue with programming.  If you're going to change the CV value anyway, you don't need to know what it is.
