My guess would be that the music files are in fact protected, as copy protection prevents you from modifying the file in any way. Since you're not allowed to circumvent, crack, etc copy protection, your best option is to pop the CD back in and rerip it using different settings. For instance Windows Media Player automaticallt rips using WMA with DRM I believe...just change that to WMA w/o DRM or MP3 and rerip...all should be well again.
Hope this helps,
i have ripped songs of a mp3 CD i have and when i try to change any file's info, my comp. doesn't let me !!!
what could be the problem -- protected file or something?
how do i go on about solving this problem?
