OK, got a Creative Nomad Jukebox Zen today, a refurbished 40Gb. I set it up with the creative software, it worked fine put across 4 albums, then took it off just to see how it sounded. Then when I fixed it up to my computer again, none of the Creative software could recognise it, MediaSource and PlayCenter. I have re-installed the drivers, and the software but still nothing. When I install the drivers, it comes up saying there is a problem with ctjb2sp.dll. The computer recognises it is connected, the creative zen screen shows that it is communicating, and MediaSource even has it appear on the device bit, but then says that it isn't connected. Has anyone had this problem, or know of any solutions? They would be greatly appreciated.
