Not answering, not formatting, not upgrading


So I’ve got a serious problem. 

My Clip v 1.01.29 is crushing.  I can’t delete anything from it via WMP or USB, I cannot write anything on it. The device cannot be formated. It says that everything is OK, but after a reboot all data recovers. I cannot upgrade the firmware (it just fails with an error). Soft-reset does not help.  

And Clip itself became sooooo slow, that it’s impossible to work with it. In everything else it works completely fine. 

I’ve tried all the things I found at this and other forums and nothing helps.  

Is there a cure? Or I need to return it / fix it in a service? :frowning:

sorry for the english if something’s wrong.  Thanks for your help.
