Sapling Add On

Hello,

I am using Blender 2.70 and when I try to use the add curve, sapling option the tab appears with some options but I do not have anyway of viewing the object tools tab with the leaf options and extensive tree features? I just have the regular vertical tabs and have never had a tab named “object tools” like I have seen many people using. When I press T it simply toggles the vertical tabs. Any help is much appreciated!
