NO FONTS WERE FOUND ERROR

I am using Corel Graphics Suit 8. It used to run fine but yesterday when it was not responding I force closed it and since then whenever I try to run it, I get this error "NO FONTS WERE FOUND. THIS APPLICATION MAY NOT HAVE BEEN PROPERLY INSTALLED" and it stop running after that. I un-installed and installed it again twice after that but still getting same error again and again.
