Please refer to the attached screenshot. Is the underlined path is relative to which file, Xojo or Valentina plug-in? Because I did what you suggested and still the same. I even modified the (underlined) path and added "C:" to it but still the same. The thing is, I installed Xojo in drive D: I uninstalled everything, Xojo and Valentina plug-in then I installed Xojo this time around in drive C: Viola! Now everything works! Thanks!
