Here's what I'm seeing.
That's a good indication of corruption right there. First I'll ask a question, and then give you an answer.
Was HC Sim like this from the very start (it never worked) or did it do this sometime later (it was working and then at some stage later this happened)?
It it was previously working try this: In C:\ProgramData\RingEngineering\RailPro HC Simulator\ delete the file RscLoaded and then try HC Sim again (this file seem to be the usual culprit). If this doesn't fix it then you'll want to delete the storage file (HC Simulator Storage) and reinstall HC Simulator to recreate it.
If it never worked we'll sort that out when you get back.
