Oh boy, I hate being the dumb newbie...

Please don't write me off just yet, but how did you get to that selected directory screenshot?

You know when i'm in Options-Tools-Sharing, there is only the button ADD for me to click on, or underneath there is a thing l about shared extensions

One other thing, might be important but when I'm in Options-Tools-Saving page and I click on browse to save files to a new folder nothing happens there either..

Thanks for your patience
