I think I should go out and purchase ZwCAD. At least I can get help there.
I have been trying for hours to solve my problem and get no response.
I have tried the LTU and get message serial number not valid. So I looked at others similar problems and tried toget a new serial number. I cannot get by other requests for items I don't have.
I haqve used Autocad for 35 years and never had problems like this!
