TidyPics Admin Portal

Hi Guys

Im fairly new to elgg but have successfully installed a number of plugins.  Ive attempted to install the tidypics plugin which installs and allows me to enable without any issues however upon selecting the tidypics administration link i get the "Oops sorry this link appears to be broken".  I have removed the plugin from mods and re-uploaded but the issue still remains do we need to install this plugin any differently to the others?

Any help much appreicated.
