Last night I posted a message concerning my frustrated inability to solve the problem of frozen window and no usb seen on the PC. I noticed someone suggested a faulty power cord so I tried this option by holding down the center button and re hooking up the clip again. It worked such that I could see the device. However… as soon as I tried to then get it back to normal to see if I could play music or FM after disconnecting the computer it was frozen again… no the thing was not locked! I then tried the same process all over again and I could NOT get the thing to reset. After several tries I went back to the Macintosh… restarted the macintosh and then did the hold/center button thing again with the lock on and low and behold the mac with OSX could see the device! I was able to see the device connected with the computer on its tiny screen. However, I have NOT as yet tried to trash the icon and restart the device in non-conneected to the computer mode. I would prefer to somehow reset the device from the computer and start all over… is that possible… many hours into this process already… I just noted I checked in on 167 messages!
