At the time to open the Scada Data Gateway, it shows an error like:  "An error ocurred when accesing the license system. Error: getAvailableKeys():adminGet(seat):LmNotFound ..."


There is an instance called Sentinel who manage the SDG license, probably its service was stopped and license cannot be found.
Open task manager \Services Tab\ Service is called "hasplms", start or restart it.

Open again the Scada Data Gateway and check if the problem appears. 

There is a log file where you can obtain even more details. "C:\Users\Public\Documents\TMWSNLicLogs"
