I don't know precisely to what you refer as there was no reply from any users to your post. However, if you haven't opened a support ticket yet, I'd suggest you do so at
http://www.ikmultimedia.com/contact-support and they will be able to assist you with your issue and get you up and running with MODO DRUM.
Users may still chime in but the best way to resolve any issue like this would be through direct technical support (and this forum is not a medium for direct tech support).
I am sorry to hear you are having issues, but I am sure they can be resolved by the team.
Thanks!
