go back to originaloriginal default settings

It it upsetting to say the least that I cant go back to the original settings that I started out with. I have been all over the place with videos that claim to solves this but they don't, they either show me buttons I don't have or have gone somewhere else and without knowing how to get it back how the heck can I click it. something is always different and since I have to use help videos to learn I would like to be able to keep things the same.

I want to take the format back to the original settings that I downloaded. I try to go to effects and it is either not there or it is off on another area of the screen.

Its confusing at best.

I want to take the program back to the original settings. the alt shift don't take it there. I am about ready to try someone elses editing program just for this jumping change of format that I cant go back to where it was. very upsetting.

any help will be helpful

Thank you,

Tom
