Sansa Clip frozen on startup screen - can't reset, can't update firmware

yes, I am having the same problem.  it was working, then locked up, reset about 10 times, finally came back for one training session, then during my session it locked up and said refreshing media, now it is stuck on the login (clover) screen.  

I am using Media Monkey to setup a playlist, not sure if that is causing the problem.  some kind of corruption, but again, since I can’t get the PC to recognize it, I can’t even reformat.  

Also, i have a micro sd card.  I removed that to hope i can reformat, but still locked up.    This is not the only time OR SanDisk MP3 player that I have had this problem with.     

The only Sandisk mp3 player that I have that still hasn’t crashed is my old original 4 year clip, all the new ones have bombed.  ugh!!!
