I am unable to sync music ripped from CDs to my NWZ-E474 Walkman. Whenever I try to sync tracks, the sync status simply states 'error'. Songs downloaded online (which I do not have many of) are syncing on to my Walkman no problem. I do not beleive the sync error is to do with the copyright protection on the CDs, as I have been able to rip and sync music from them to previous Walkmans that I have owned. Is there any possible solution to this issue? I am not the most technically minded individual and any help would be appreciated.
