The rest of the error message should tell you exactly when you can obtain yet another certificate.
Yes, by not getting a new certificate almost every day. A cert is good for 90 days. In normal use, it should be renewed after 60 days. There's no valid reason to be issuing new certs daily.
You can reuse an existing certificate (you should have one at C:\Program Files (x86)\TSplus\Clients\webserver) and there is a log file you can look at for more info.
Just at guess I'd say it's acquiring the cert but either not managing to save it to disk or not recording the last renewal status, becuase for some reason it keep strying again even though it already succeed. Check you have enough disk space etc and the paths are writeable.
