Dowloaded / copying a xbox game?

Hi

I do apologise if i'm asking a question thats been asked alot before but u have been looking at a lot of threads on here and all the links no longer seam to work,

I have downloaded a xbox 360 game from a newsgroup have the iso file but on here it says i need a ss.bin file for this game if it doesnt come with one so i opened the file in xbox 360 ss manager 1.7v it says the current ss is 412E817F02075ED398064BD78ED2330E is that what ss file i need to find or am i just missing the point completely ???

Many thanks for all your help in advance
