Hmmm. Read the game was free to try out before purchasing. Guess that wasn't true since it will not let me in to either server until I buy it. Looked like it was worth buying, but since I cant get in to try it, not sure now.
The last update Xsyon changed it to pay to play only. You must by the game to play it. Once you buy it you get a free month of premium time, after that time you can play it for free each month as non premium.
