Oh man, I bet you're frustrated. Hope I can help! First, I have never, and don't plan on doing what you're trying to accomplish. So, I don't know the ins and outs of the Zen. But, I deal with sync issues at work all the time, and can relate the issue to what I do.
Before we try to uninstall WMP 11, let's try something else. I take it you are syncing this through usb? If not, and using bluetooth, I'd try usb if you can. Bluetooth is much harder to set up with syncing. If it is through usb, I would first try deleting it's profile. In device manager, find where it is, and uninstall it. Alternatively, you can try uninstalling the USB Root Hubs under universal serial bus controllers, and then doing a restart. Make sure your mouse or keyboard isn't usb, otherwise when you uninstall one of the roothubs, anything usb will stop working until you restart your comp. After the restart, once you plug in the device, it will be recognized brand new again, so any corrupted or screwed up hardwire profiles it had in the past will be eliminated.
Try again. If that doesn't work, and you want to try the reinstall of WMP you should be able to uninstall it. If it's not under Programs and Features from the control panel view - try looking in "Computer" - "Program Files" and then it should be under Windows Media Player. Just delete the whole folder, and try installing it again. That SHOULD do it. ZEN support should handle the issue though. I don't even know what a Zen is, but they should have a higher tier that deals specifically with sync issues.
Good luck and hope that helps a little!
