using ezDrummer offline?

I have registered this product and activated, but when I launch it with no internet it wants to authorize again,
kinda annoying.  I hate software companies which are doing overkill security steps with their products.
This like asking for "crack me up" or "go away" to customer.... 

Have you downloaded the latest version. I'm sure that gets rid of this little quirk, which is a known fault with Toontrack stuff. If that fails, post on their forum, which is answered by their employees. As I said, this is not new so there will be a solution.
