Grasshopper error message on start

When I type the "Grasshopper" command in Rhino command box, this the message I am getting:

Or in text:

---------------------------

---------------------------
Exception occured during processing of command: Grasshopper

I am using grasshopper 0.8.0050 and Rhino 4 SR8. I tried uninstalling it, and then installing it again. The same.
It is interesting that until yesterday, everything was fine.

What could possibly be the cause of a problem?

Thank you.

The obvious explanation would be that the font was modified. It's very strange though Segoe UI is a windows native font and it most definitely should support Regular. I attached the font, try installing it and see if it makes a difference.
