I did an install on this the other day and didn't have time to spend working it out. I deleted the checkout and purchase pages as they showed up on the top level of my site.
Since then i've gone back in and firsly deleted the plugin, then reinstalled it, but I can't get the checkout to work. I can add the product to the Download Cart widget ok, and test the page, but when i click on 'Checkout' to test it, nothing happens.
Any help would be appreciated as this looks like a great plug-in.
