cannot open document and message says "cannot be opened. Try again or repair the product in control panel." Did that and was told repair was not successful and to check internet connection. Definitely connected to internet. Was going to try to uncheck the IPv6 protocol, but can't figure out how to get there - can't find Network Adaptor Settings. Or, should I do something else. Thanks for any help you can give this old broad, cause I'm feeling pretty stupid about now.
