Cubase 5 not starting correclty. QuickFontCache not found?

Hi everyone!

I need help with a recent problem that has been occurring with my Cubase 5. When I start the program a notification comes up saying QuickFontCache not found. After you click “ok”, Cubase 5 says not working and crashes.
If you have solutions to this problem I would really appreciate it and can tell me how to fix it I would also be appreciative.
