Hi to everybody! I have some problems with the visualization colours associated to lines, surfaces and volumes: specifically, I have modified the colours of lines and volumes in preprocessing by putting it black in Preferences -> Graphical -> Colours in order to have a better surfaces visualization (the structure is composed by hundreds of volumes but I must define the mesh parameters on every surface); now, I can't return to the original visualization because the colours section is not loaded (photo) and a message appears: "Problems while checking actualizations."; I have already try to uninstal and instal again the software but with no changes.
thanks
