Resetting to default

[khat+ 0]

I think I may have installed pagelines pro incorrectly, and then used features incorrectly. I installed first platforms framework theme and then the child, thinking I could do setup for child later. I tried to set up a background image, and tried custom css feature in pagelines dashboard. I had mistakes in my css, and just thought that if I deleted the info in the css custom feature in pagelines dashboard that the new information would overwrite the old info. The background image didn't respond at all, probably because I didn't have the child directory renamed. I then tried to use the LSS plugin to create css and added more css, possibly, somewhere -sigh-. I never did change the background image and get it placed properly. I used a workaround and in nested containers I placed a background image which worked well enough, so I moved on to try to create my nav bar/ menu bar. When I go to the Menus panel, there is NO area where I can place a menu on a page. I have read and reread and re- re- reread the instructions for placing a menu. I've used the pagelines editor to place a menu, however only HOME shows up. I've been at this for many hours. I've since uninstalled all of my pagelines items and reinstalled, thinking that it would restore all my changes to default, but no, it is still all there, with all my unresolved issues. I am completely at a loss as to what to do next.
