Cubase 10.0.50 problem

After starting this message appeared. Also, audio files cannot be imported. I uninstalled cubase and installed an older version. Same. Where is the problem?

Hi and welcome,

What exactly do you mean, please? What does it mean it cannot be imported? What happened instead? Any (error) message?

What kind of file do you try to import? WAV (count of channels, sample rate, bit depth), MP3, FLAc…?

What method do you use to import? File > Import > Audio File? Drag and drop from desktop? Drag and Drop from MediaBay, Import to Pool…?
