We had a license issue with Ornatrix for Maya. I don't think this is related. Have you been able to solve this in any way?
You might try to install just the license server from the "Install license server only: Previously licensed computer" link on the Downloads page (for your OS, looks like Windows).
You can also look at the https://ephere.com/licenses.html page to check your existing licenses. Have you ever installed other licensed Ephere products? (demo versions do not use the licensing system)
If you can't make it work, I'll have to ask you to try some commands from the Command Prompt.
