technosat T-800 PLUS

My Satellite Setup
Technosat T-888

Hey guys:

Let me say first that I’m a newbie. I have a tehnosat T-800 PLUS. I found this website It contains a lot of receivers’ softwares. The problem is that I found like 4 softwares for the tehnosat T-800 and I can't decide which one to download. Anyways, I downloaded the T888FTA (1mb). But the channels are still scrambled. I heard that there is an activation code that I have to enter into my receiver. Is that correct? If yes, can anyone help me get it? Does anyone know how I can choose the right software from the above website? Thanks a lot guys. Appreciate all the help.
