Hi all,
OK, I'll 'fess up - I'm perhaps not the most technical-savvy person ever (well, I thought I really was, until I ventured into MP3 tag!)
I want to use MP3tag 2.42 to rename (and get some consistency) in my iTunes library. I've used Tag - Filename for all my music library, and now iTunes just shows me an exclamation mark whenever I select tracks in the library.
Ideally, I could do with a step-by-step process to help me through - and despite how frustrating this might be - hoping that someone out there will take pity and help!
Cheers in advance.

You have to rescan the files in iTunes becaue iTunes is looking for the original filename and you changed them with Mp3Tag.
