Question

Since Nov update about a third of my songs have a circle with an exclamation mark inside the circle. These songs will not play on my computer. Message says  "The song .... could not be used because the original file could not be found. Would you like to locate it?"  I have reloaded these back onto itunes with my own CD collection. They work for a short while, then the same thing happens. I don't  know what is causing this or how to fix it.

Answer 1

I finally resolved my problem after spending way too much time on it. I simply handed my 160GB iPod to my husband to put his fav Stones & Beatles songs on and I went back to my 80GB Microsoft Zune which has never disappointed me.
After spending so much time trying to figure this out I did finally take it back to Apple Store who performed a diagnostic and found there was a problem with the device. They replaced it with a refurbished one which has similar issues. All I wanted to do was listen to my music. Was that too much to ask? So I am happy to be free of this problematic device. No more Apple for me!!
