When "programing" custom tunes to the act device,.should each tune file have a unique CEF Is? Each tune I load have the same Id

mmm, like mine have "93p.cef" and "87p.cef"....but then you add them one by one and can name the tune....currently mine say "87perf/tow", "93performance"...."93perNew" (which is my final revision and I need to delete the "93performance".

You didn't try to rename the tunes when downloaded them did you, if so just go back to your email and download them again and don't change them.

(the 87perf/tow...might be 87towperf) I can't remember if "/" was an illegal character.
