workspace is messed up and presets are lost

Hi I am using Audition 2014.2.

Sometimes, almost every day, when I open Audition the workspace is messed up and every  pannel is pushed to the upper left corner of the window.

The same time, all the presets are lost and the Presets list of the effects rack is empty.

I can reestalish it by deleting the folder "user/xxx/AppData/roaming/adobe/audition", but after a while the annoying problems reaapear.

Thanks,

Daniel
