Actually I found the issue, accidentally, when demonstrating my TeslaScada application to my boss but sorry I forgot to update my forum request.
You may remember a week or so ago I had problems with Java errors when I ran my project in the simulator. That was resolved by running the IDE as administrator.
This issue has now been resolved by running the TeslaScada runtime as administrator also.
The other good news is that my boss was VERY impressed with the working TeslaScada demonstration that I remotely showed him and agreed to commit to using your product in our current project.
