im having problems on adding a background in Sorrmaker

so, im having a problem with background and layers, i watched some tutorials (there are barely any tutorials and the ones i watched barely helped me) and i cant put a background in my stages (my sorr editor has no 'layers' buttons, and theres no ground collision (? idk if thats the case) i have no idea on how to put a title screen, if that even matters) i have FPG editor 2009 & 2005, i almost dont have any basic knowledge about sorr (& editor's) technical side and the fpg editors. (i dont know if i need any plugins or smth, maybe not) can someone help me or tell me what i am doing wrong?
