Program doesnt work at all a recently intaled in my windows 10 pc tonight
how can I up grade or buy the code to activate the program I Like It but doesnt recognice my files at pc.? why
The windows version is freeware - there is no code.
So, please describe, what you have done so far, whether you get any error messages.
Because: over here MP3tag works.
In addition to the questions from @ohrenkino 
What kind of files do you want to load into Mp3tag?
For example MP3? FLAC?
Maybe this instructions can help you too:
