Firmware update went wrong
What operating system are you using? The Zen Touch firmware update will fail in Vista or 7 -- you need to run the update from an XP install. Once you successfully get the 2.11 firmware on the Touch, it will then interface with those later OS's without difficulty. Also, what version of Windows Media Player are you running? Believe it or not, this makes a BIG difference. The latest Media Player 11 will cause the firmware flash to fail, as will WMP <= 9. I have three separate players that have experienced this problem, including one that had been disassembled THREE YEARS AGO after a failed flash, and was able to resurrect all utilizing this method:
(1) Uninstall everything Creative: the driver, Jukebox, etc. Delete the Creative folder from Program Files. (Some amendment to these instructions may be in order if you have a Creative sound card -- I have built-in Realtek sound so it didn't apply in my case). A restart may or may not be required: go ahead and do so to be safe.
(2) Plug the device in after restart. Windows will want to find drivers for it -- cancel that process. Open the Device Manager. The Touch should come up with an exclamation point next to it (since the drivers were not uninstalled): right-click and select "Uninstall." I have seen instructions on the Web to also uninstall all USB root hubs, but I have found that unnecessary and a pain if you have a USB keyboard and/or mouse. Unplug the device. Restart.
(2) If you are running a version of Windows Media Player not equal to 10, either install 10 (if you have 9 or below) or roll back from 11 if you have that. Restart.
(3) Plug the device back in. My supposition is that this is particular to WMP 10, hence the problems with other versions. The device should pop up as "Creative Zen Touch:" if Windows asks to find drivers, cancel that process, and the device should now come up as an "MTP device."
(4) Since the firmware flash failed, the Zen is probably in recovery mode. Launch the firmware updater software on the computer, and stay at the language selection screen. Choose option 3, "reload firmware," from the recovery menu. It will inform you that it is "deleting old firmware" and then will give you a short period of time with a dialog saying "start firmware update" on the Zen screen. During this time period (about 2 secs), press the language selection of your choice on the computer in order to start the update. It should go through successfully this time.
