Do you confirm you had reset your user profile for your regular user???
I don't think so.
I understood novice to say that the instructions for resetting the profile were too difficult. I only suggested trying a new user as a (perhaps) easier alternative to performing a profile reset.
Working as the new user won't make a good long-term solution, but it does tell us that the problem should be solved if the profile can be reset for your normal user log in. That would be the better long-term solution.
Maybe you can ask someone who is more comfortable with file management to help you? It won't take an expert, just someone who is comfortable following the directions in the tutorial.
