How many computers can I install and activate Steven Slate Drums on?  Also, if I ever get a new computer, how do I go about installing/activating SSD on the new machine?

In your user account you get 2 license file downloads.

Each license file is good for one install.

You can have 2 concurrent installs of the software.

If you have a new setup or need a new license file please submit a ticket.

You should see a yellow "Ready!" link in your account when the license has been generated.  Please download the license and place it in the SSD4Library folder.

The license is a passive one and simply clicking on it will NOT activate your product.

To use the license file go to the SETTINGS tab in the plug-in interface and navigate to the license, once you have loaded it you will be able to load drum kit presets and individual kit pieces to kit graphic/cells.
