I have same problem since yesterday,all my files have extension nbes.
So far I have find out that simple online converter from the link : https://online-audio-converter.com/ recognize and even convert all my mp3 files and allow me to download them in any chosen format. Other converters can't find file in specific folder.
But my problems are photos, Emsisoft decryptor didn't do the job, keep saying :
Error: Unable to decrypt file with ID: T2rTkvqPawuxU1ZHaaduwWpHn6I22SeYX39M9Zt1
Error: Could not find a part of the path 'C:\Program Files (x86)\Common Files\AV\avast! Antivirus'.
