Cubase 10 pro license (pen) possibly corrupted **EXTREMELY URGENT**

This issue occurred when I was doing an internship work at the work place; I had brought my cubase license that day in case i needed to use it on one of the computers there, in which I did for some time (and everything worked fine), but I ended up using another program because it was more convenient; so I closed Cubase, took out the license, kept it and did my job. When I came home later that day I planned on starting cubase for some other important projects and it doesn’t start anymore; it keeps saying the same message: "eLicenser Control - Error: Application ‘Cubase / Cubase Artist’ has caused the following error:

DCOM connection to program ‘Synsopos.exe’ failed.
Error:Unspecified error

I honestly have no idea how to fix this, so if someone could help me I’d be really thankful. I really need this problem solved so I can resume with my projects (they are REALLY important!!!).

Thanks,
Gui

What is going on with this issue? I have it too and have not been able to fix it.
I have not been able to use Cubase for 6 months now and started using Mixbus.
Why does Steinberg sell software that you can’t use? Why don’t they fix this?

Did they fix this in the new release Cubase 11?
