miklos, try to delete your DoF profile
To fix this you would need to delete the Local Saved Data File
1) Click on the organizer button in any folder. And select Folder and Search options. Go to view, and under Hidden Files and Folders, or Drives - click show hidden files.
2) Now navigate to C:/users/YOUR USERNAME/AppData/local/DoF/
3) In that file, locate and delete file called local_saved_data and interfacedata.dat
