I have had my nano for a few months and worked fine. Then I sent it in for servicing. When it was returned it worked fine, for about a week. I tried to add pictures to my nano and I keep getting the same error message "The ipod "dymond's ipod" cannot be updated. The required file cannot be found. I sent my nano back in last week, and when it returned the same problem occured. I have tried the five R's and it hasn't solved my problem. Please someone has to know what to do to fix this.
