I've got a Rowe CD100 where disc 21 shows up as "not allowed" when you try to play it. I just installed the MP3 kit from CDADAPTER and ordered a hard drive from them as well. The HD is just fine. I've tried multiple delete and copies of different mp3s into the folder, renaming and creating a new folder, all with the same result. I've e-mailed them and A and B jukebox to see if they have any ideas as well and hope to have responses soon on that end.
Since I had the unit filled with cds before and they have gotten dusty over time and some may have had scratches and what not on them, I've done a ton of things in the service menu. I've cleared out all the errors, cleared out the disc conditions, checked the lockout to make sure nothing was listed in there, set the disc limits on disc 21 for the number of songs that it has (20), did a full initialization, did a single disc (21) initialization, and all of those multiple times with no change. Disc 21 is still "not allowed" when you try to play it.
The CCC board also has a coin type battery on it. I've had this jukebox for about 8 years now. I did pull the board out and check the battery for corrosion or leaking just in case, and it is in great shape with no issues there. I've never had an issue loosing settings, so the battery is still helping to retain all of that information as well.
If you've got any suggestions on something else I might have overlooked in the menus, or other ideas to try that would be great!
Thanks!
