Go to the Harris Premiere website and find a number from there.

You'll need the serial number from the DPS hardware board you're using (it's usually on a sticker on the board itself). You'll also need to go into the DPS hardware utility from your Control Panel and write down the Hardware ID.
If you have these two pieces of info, Harris should be able to send you an software unlock key via email.
You might have to register to get the phone numbers you need, but it's free and there is tons of software on the site for Velocity products as well.
