Software downloaded - Are keys needed? Which ones and where from?

My Satellite Setup
motorised diseqc 1.2 superjack motor, 1m dish, 0.2db lnb, topfield tf3000cipro receiver
My Location
West Yorkshire
I have a topfield TF3000cipro. I have downloaded the firmware from the topfield site. What is my next step. Do I need to get some keys to get the most out of the software or does it start to work automatically. If i need keys where do i go and what do i look for?

Secondly i have heard about emu software. What does emu stand for and what does this software do?

Thanks in advance for any comments.
