Filename trouble

In Dopus 9 sometimes the program displays filenames oddly.
For instance Barbershop.mp3 turns into BARBER~!1.MP3
It does that for all the filenames and foldernames. Does anyone know how to fix this?

Your installation may be corrupt. You may want to download and install the latest version.
