Hello, it seems MP3 diags is a very powerful and useful tool to fix tags, but also very non-straightforward, and the documentation is confusing or not suitable for newbies.
Would you mind giving me the yellow brick road on how to use that program specifically for the task of fixing broken ID3 tags? I don't care for the other possible fixes that it may offer, and it's very hard to understand, because the creator offers very little explanation for starters on when and how to use them. Basically, he used his expertise to create a program that only he knows exactly how to use, and made it impossible for anybody else not at his level of expertise to use. In other words, he didn't worry about translating his rocket science to a language that lay people, mere mortals and heathens could understand.
Asking cause I gave up using the much simpler Mp3Val, it chokes on small list of files, and even the files that it can scans it stalls and freezes in the middle, so it's small size is also followed by small power/stability.
