Files not loading in Mp3tag

Hello.

I've been using the software for several years and this is the first time I face an issue. But I do believe it's some problems with my files, and not the software itself :confused:

I tried to load some files today from the folder below. I created them with Audacity and they play without any erros in my music player (currently, I'm using Media Player Classic).

When I try to load these files into Mp3tag to edit their tags, the software is not able to do this. This is the first time in many many years that this happened to me, even though the process I've been use so far to create my files (download music files > edit them in Audactiy > tag them in Mp3tag) is still the same.

I searched for some solutions here in the forum and bumped into Mp3 Diags. I run the software on my files and got the notes below on all of them.

Now I'm stucked and don't know what to do or what it's causing these errors :confused:

If I see that correctly in the first screenshot then you have applied a filter with / and 5 files have been loaded but 0 are displayed.

Press F3 to toggle the filter.

That's the error. I can't believe I was that stupid not noticing it.
Really sorry for wasting your time, but thank you anyway!

That's why it is that important to show screenshots (as you have done!)
Sometimes it's just a single character...
