Help With Windecrypt105



Hi all,
Its been a while.
I am just wondering if i still can use the above program to watch **-digital?
If so, could some very nice person tell me how to use it, as its been that long, i have forgotten.
I think i have put all the basic stuff back in, like the channel id's and the monthly keys, but i remember i have to set my com ports up or something like that?
Also, where do i enter my own management keys and ppua?
Many thanks,
P.s sorry for sounding so thick, a quick lesson would be nice again.
