OPCUA Simulation Server runs in background; no HMI dialog

I installed the simulation server a few weeks ago, and I had no trouble running it normally. I could see all of the details I wanted using the Basic and Expert modes in the HMI. After a week or so of not running the tool, I started it again (perhaps 4 weeks after installation), and the process UaSimulationServer.exe shows up in my Windows 10 (64-bit) Task Manager, but no GUI interface appears.

I have uninstalled and reinstalled the server, but nothing helps. Any suggestions?

Thank you,

Hi Doug, You may need to reset the configuration. Move or remove the whole directory %USERPROFILE%\.prosysopc\prosys-opc-ua-simulation-server\ after clsing the server (kill the process if necessary) and restart. You could zip the whole directory before that and send it to simulation-server-support at prosysopc.com, so we can check what had happened.
