Ok, are you sure your supplier has offered you a sat line and not a VM/cable C line as this won't work on that box (don't post any line details here)
Did you save the line as CCcam.cfg format and not a .txt format as this won't work?
In the folder usr/keys, there's only one instance of CCcam.cfg? - if there's two and your line is in the one named CCcam.cfg (1) this won't work
was your line in this format:
C: server 11111 username password
