Pay Per View not working on fresh install

I couldn’t get pay per view plugin to work previously, and I was assuming it was my theme or something else I had messed up. I installed a clean install of WordPress along with a fresh download of the plugin, created a test post inside of twenty-eleven default theme, tried protecting it in several ways. Have no problem protecting it, it then takes me to the Paypal checkout, and after successful payment I am still locked out of the post.

Not sure where to begin trouble shooting at this point, as everything is fresh and empty. I have it set up on a sub-domain just for testing and would be happy to provide any credentials needed for someone to look a bit deeper for me.
