What next?
To install:
Open the Zip file. Assuming you're on a Windows system, Zip support is included in the OS. If you're not on Windows, the download won't work for you.
Inside the Zip file is a folder. Extract that folder to a convenient location. I dragged the folder to my desktop, which extracted it there.
Open the extracted folder. There will be several files inside, including setup.exe. Run this file.
Follow the prompts on the installer, then stare at the shiny new screenshots and listen to the nifty new music while you wait.
Once it's finished, it will have the option of running the GR beta. Leave that checked, and click OK. This will start the Beta Updater, which will checksum the files and check for new updates. When I ran it, there were no new patches to download, but by the time the Loyalty Program gets in, there may be.
Once you're installed and updated, all you can do is wait for the server to open up for the Loyalty Program. When it does, you should be able to log in just like you do on the regular servers or the test server; as far as I know, they didn't change that part.

Evening all!
So what's next after downloading the client for the Loyalty Closed beta? How do you install it or make use of it?
