Draftsight suddenly refuses to start

Without any changes to my computer or software on it, I have experienced a problem with Draftsight (2019). When I try to start it I get two error messages 1.) Activation Wizard initialization issue: 72 and 2.) Cannot obtain a license for Draftsight. Please contact technical support. I have tried to find a way to contact technical support but there does not seem to be a way to get an answer.
