adding packages
 

I wanted to add a kobold press package to my license but there wasn't a "hperlink" to add it to a cart? how do I add extra packages?

Are you logged into the Purchase Data Packages page? There should be checkboxes next to any packages that aren't already on your license. Scroll down to the Pathfinder/Kobold Press section, check the checkbox next to the package you want, scroll to the bottom and click the Checkout box.

And to foot charlieluce's sound advice: to start, enter Hero Lab, go to the License tab, then scroll down and select "Purchase Data Package..."
