TTtoolbox tools not in grasshopper tab

Hey all, 

Downloaded the file and copied the Toolbox folder into the correct path for grasshopper. I followed the download instructions, and I right clicked to unblock them (files). I am running Windows 7, and in GH it shows the folder TTtoolbox is there in the special folders\components directory. It just isn't being recognized by grasshopper. The toolbars do not appear in the tabs. Any help or suggestions would be greatly appreciated!

Thanks,
