2014r2 and Chilkat ActiveX no longer work together

If you try and compile an app that works fine on 2014r1 and r1.1 that uses the ChilkatSoft ActiveX it works great but as soon as you try and call the unlock code for Chilkat in 2014r2 you get a nil error and the Chilkat classes stop. I have contacted Matt at ChilkatSoft to see if he can find out what has changed in 2014r2 to mess this up. If anyone has come up with a workaround can they let me know.
