Can't save Progyect templates nor any king of presets

When I use the window to save project templatas o tracks presets, and push the Accept key, nothing happens.
The window is not closed and the file is not saved.
On the top of the window the arrows do nothing , the New Folder don’t work too

I’m using Cubase Elemets 9, but in Element 8 Trial have the same problem.

Any help?
