Hi, I have a different Hi-MD wav importer problem. I had been happily uploading .wav files from my Sony MZ-M100 Hi-MD recorder to my PowerBook running OSX 10.4.6 via the USB port and Sony's Hi-MD WAV Importer. (SUCH an improvement over playing audio out the minidisc's headphone jack!!) But something happened (perhaps, despite my efforts, I disconnected the MD-to-Mac connection when I shouldn't have...) that caused the connection to freak out. Now after repeated attempts, I can't get the Mac to recognize the MD at all (via either of two USB ports). Anyone else had this problem? I reloaded the wav importer software, and that worked until I (very properly) disconnected the recorder again. Now I'm back to square 1 despite reloading the software more than once. I can still play audio out of the minidisc and into the Mac, and I can still successfully hook other devices (like an iMic) up to the USB port, but the fast digital connection seems to have evaporated. Any advice? Thanks--
