Went through the "communications" tab, "send to remote" function with no errors. All the pages appear in the remote as normal, but none of TV/components respond to any of the functions. I believe the sending indicator lights up when I push a button, but none of the components respond.

I'm surprised, because I barely changed the file. All I did was add a back button to page 1 of the cable functions, using codeset 202 (for Comcast Xfinity box), and then went to "communications" and "send to remote." Yet that small change now results in none of the remote's functions working.

Yet when I open up the old, unrevised CCP file and send that to remote using the exact same method, all the functions are restored and everything works normally.
