I am the owner of both a 4GB and an 8GB Sansa Clip. I’ve had the 4GB version for well over a year and I’ve always used Winamp as my PC audio software of choice. All of my MP3s have ID3 v.1 tags and until recently, the Clip was able to read them. Then all of a sudden one day, everything went into the “unknown” category which is unacceptable. I can’t think of anything that changed. I never upgraded the Sansa firmware version or changed my ID3 tags for my music. I never upgraded my version of Winamp either, but just for kicks I did upgrade to the latest version and the problem persists. I’m also have the exact same problem with a brand new 8GB clip that I just bought last week. Nothing I try is working. Can anyone help??? Thanks.
