First of all: I use a Mac, so I don’t have any of the software used to transfer music. I just drag and drop. (this may or may not be relevant, I just wanted to make sure all the bases were covered)
The problem: I just transfered a new album to my player and then deleted some other albums that I wasn’t listening just to free up some space, but down at the bottom of the window, it was telling me that I wasn’t freeing up any space at all. (on a Mac, it tells you how much total space is available down at the bottom of the window) The actual MP3 player was also giving me the message that said “Not enough space for music DB. Please free 90 MB”. So, I unplugged it and re-plugged it in a couple times, but every time I did that, the total free-space slowly got lower and lower until it was telling me that I had Zero KB left. !!! Please help, I have no idea what might have happened or what to do!!!
