No, I did not receive messages either.
So that concludes what i have been saying from start that the plugin is not loading and you are debugging the menu. Now if all is well i would attribute this problem to using wrong libraries linked to your 64 bit plugin project. Make sure all the 64 libraries are being linked to. You could ensure this by renaming the 32 bit library folder in the sdk, in case your project is referring anything inside this folder the 64 configuration will cease to build and you have your solution.
Let me know if this works
