I can't get my installed program to open.

I had not opened Rosetta Stone in at least a year. During that time I upgraded my OS to Sierra. Now when I try to open the program I receive a message indicating an error. During that same period I changed my email address from *********@ sympatico.ca to *********@ cogeco.ca and I fear I have forgotten my password. Please advise me how to open and use the program.

MacBook Air, macOS Sierra (10.12.5)

Computer Won't Accept Password Just got a new MacBook Pro and I'm jumping through all the hoops, entering my password again and again for one box after another, and now I'm down to the last one: macOS needs to repair your Library to run applications. Every time I enter my pass word the box disappears for a fraction of a second and reappears. Same result when I try to cancel it. Of course, I can't do anything with my new computer until I fix it.
