I have not used DT for a while. I run it on an old MBPro as a repo for older academic work. Today I wanted to search the repo and DT will only launch its registration window. When I enter my licence details it warns it has an invalid certificate and it might be an insecure server.
Please tell me how I can open the software I paid for. I know it’s old, but it worked fine on this computer last time I opened it.
Thanks.
