Hi niiyeb, welcome to the forum. What image do you have loaded?
Do you have a FTP program, like Filezilla? If so try connecting, to your receiver, using Filezilla, or other FTP program. You will need to know your receivers IP address to do this, check the receivers menu for network information. Once you have connected look for the CCcam.cfg file, right click on it, select the view/edit option, paste your lines into it, clearing anything currently in it, then save.
