Yesterday DraftSight was working just fine and now today I wanted to use it and it doesn't work and has a message in the command window:

Substituting [arsimp.shx] for [gothic_f.shx]

Substituting [arsimp.shx] for [gothic_f]

An unsigned add-in, DSHomeByMe.dll, has been detected, and will not be loaded. Only signed and authenticated add-ins are permitted.

Error loading C:\\Program Files\\Dassault Systemes\\DraftSight\\bin\\addins\\ImageTracer\\ImageTracer.dll add-in file

This is DraftSight Standard and I know it was only \\\$104.45 but I expect it to work when I need it.

Does anyone know what need to do to fix the problem?
