I had the same issue with this pack.
Open the Pack tab in the Content Manager and scroll down to the Super Tools thumbnail. Right click and select "Uninstall Content". The thumbnail will turn to a B&W image with a small green cloud logo. Double click on the thumbnail to install the pack and after that everything should be as expected.
