Issues configuring Toolbox

Hey all,

So i have had to reinstall my SW 2013 SP3 and for some reason when i try to launch the toolbox in requires me to configure it? It seems strange that i didn't have to do this before! Anyway, i have gone through the process of configuring it (i think) but despite this it still doesnt enable me to access toolbox, and every time i try to it wants me to confiugre it again. Toolbox is checked under the add-ins menu (including to launch at start up) but dispite this i am having no joy. I know i'm not the first person to experience this issue, and any help will be appreciated. Below is a screen shot of what i am getting.

Thanks in advance

Luke
