So I think I deleted something I should not have. I have had zero issues loading and reloading my SD card and playing sequence through the MP3 player. I was down loading sequences tonight and couldn’t get it to work, so I deleted everything on the SD card then realized I had another flash drive plug in and every time I was downloading it was going to the flash drive not my SD card. So I removed the flash dive and tried to start over now they write to the SD card but when I plug it in to the MP3 player nothing no lights no music. I can see them when I load back on to the computer. Any help would be great thanks.
