What happens when I run out of decodings?

Sorry for the basic question. I don't speak German very well, I have just started to learn this language and I thought that films in German may help me. But there is one thing that I don't understand: I have 10 decodings when I register, and what happens when I run out of the decodings? Then I wouln't be able to watch any films I've downloaded as they will be all coded, wouldn't they? So in fact I can download only ten films, as un-decoded films are totally of no use. Please explain it to me in English. Perhaps there is an answer to my question in German but I don't understand German enough to find this answer :(
Thank you in advance for your help :)

There are 2 possible subscriptions, 5 decodings/month for free (Beginner Status) or 125 decodings/month (Premium) for 50GWP (100GWP=1€)

The website should be fully available in english

There is an additional possibility to click ads and earn GWP-points for a premium account (with 50 decodings/month), but this would require 200 bannerclicks/month...

Let me give some additional information: Every user status runs for 30 days, then it ist renewed. As a beginner, you will have 15/10/5 decodings for your 1st/2nd/all following periods of 30 days.

If you need more decodings, you have to get the Premium status as dmjr has written above. If you should decide to get a Beginner staus again after having Premium status, you'll have again 15/10/5 decodings.
