So I was having issue finding the registration email so I mistakenly created a new acct. I have now found my registration email and want to use this. But i'm stuck at the screen where it's asks me for my activation key. I want to go back to the screen where I can login again. How do I do this? I've deleted all instances of "parallels" using - sudo find /Library/Preferences -iname "*parallels*" -delete - sudo find /User/my-user -iname "*parallels*" -not -ipath "*download*" -delete I've also delete the app that's created in /Applications. BUT I'm still stuck at the activation screen. Any ideas on how to get out of it and restart my installation process?
