Cover display problems

Sascha747

Dear Native Instruments community, 
I have the following problem:
I edit my music with MP3Tag. 
Recently I have had the problem that Traktor no longer shows the 
cover arts for every track, even though they are saved and are also shown 
to me in the MP3 tag. 
All cover art are jpg or jpeg files. 
Does anyone have an idea what could be causing this? 
Because I can't find any mistakes.

Best regards

Sascha

For mp3tag I save my covers again with XnView in jpg.

Now are all readable.

Was ist das für ein Programm?

Gibt es in Traktor versteckte Ordner die alte Daten enthalten die man entfernen bzw bereinigen kann? Das Problem mit den Covern ist vor zwei Tagen ganz plötzlich gekommen. Vorher hatte ich diese Probleme nie. Deshalb meine Frage.
