When I try to start the program Notenkraker it will not launch, as it used to do before. Launching from a terminal produces this output:
Looking for python... 2.7.15rc1 - wxversion(s): 3.0-gtk3
(wrapper.py:16031): Gtk-WARNING **: 10:53:30.531: Theme parsing error: gtk-widgets.css:1214:18: Not using units is deprecated. Assuming 'px'.

The problem seems to be with winemenubuilder, which for some reason seems to be 'deliberately disabled', but the link only leads to a 404 Error. Searching the documentation or this forum could not help me any further either. The winemenubuilder.exe component is installed in /drive_c/windows/system32 and has 0775 permissions.
