I am trying to register my copy of VDL2.5 and I have a fairly new mac.  For the life of me I can't install the service center, and as far as I can tell nothing has been registered.  Is this a total user error, and if so, please tell me how I can remedy this.  Thank You!

Why do you keep posting in the VDL 1 section?

Here's a direct download link to the latest version of Service Center.

if that link expires, go to the ";unprotected updates"; section of the native instruments website.
