sound tools 3 using a bin file

[Paul3480]

I just purchased sound tools 3. Everything is fine when importing an mp3 file, but when doing the same with a bin file I get 0.00 unless I click on the vocal remover tool, After doing so the bin file will process and I can make changes to the key or speed.
I am confused
I don't understand I am not looking for any vocals to be removed. As there aren't any vocals in the track in the first place
