Based on the error information, it seems that you're trying to use a resource that isn't available anymore or has been removed from sharing. The program doesn't know what to do and gives you a runtime error. I would check all the objects and items loaded in the software, because it's possible that some of them are not available anymore, therefore, the error displayed. Additionally, repair the installation using the original setup package or use the repair function available through the Control Panel > Programs and Features > Uninstall a program.
