I am SO GLAD to have found this thread! I have the exact same problem with my new 4GB Clip Zip. I use a Mac computer, and followed closely the online instructions for set-up. I continued, and began to transfer songs into the Clip Zip folder, when at a certain point I got a message that the folder was full. I ejected it in the only way I’d ever known how to do (the 3 options are clicking on the “eject” arrow in the computer’s menu bar, pulling the item’s icon into the “Trash” bin or pushing the “eject” button on the keyboard," but by then the screen on the Zip Clip player was blank. When I pressed the “on” button on the player, the Zip Clip player came back on, and showed the message, “Not enough space for music DB. Please free 200 MB.” I’ve since read in this Forum and have tried pressing the “on” button for well over a minute… it simply comes back on, displays that message and goes blank again. Every time. I’ve charged and re-charged it, but haven’t yet charged it for an extensive (overnight) period of time. That will be next. I have NO access to a PC. I purchased my Sandisc product from, shall we say, not a traditional store, but it was sold as “new” (please don’t razz me, I know, I do know…, sigh…). I’m very intrigued that the 200MB is precisely the same here. Any other helpful info. that’s been culled since this thread was begun would be very helpful and appreciated. Thanks!
