Help with gimp layout

  • I stupidly clicked close on the toolbar on the right that deals with layers and now no matter if I close down the program and open it again it's still gone. I tried to change the system preference in order to get it back but then I clicked on restore defaults and now the toolbar on the left is too long for me too see properly or set back right as the area used to change the size of the window in far below my computer screen. I deleted gimp from my computer (by dragging the app into the trash and emptying it) and then downloaded the app again and installed it but it's still the same!
    Please help me. I have pictures for a client that need to be finished very soon and I'm already a week over due!
    Thank you
