Toolbar and Libraries are gone

I opened up my rhino 4 and all of the toolbars are missing. I am only able to type in or use the drop down menus to do any sort of command. When I go to load toolbars it comes up with an error saying the library is missing from files. Am i able to just uninstall and reinstall rhino without any issues?

Hello - please try ToolbarReset - does that get your toolbars back?
