Adding a paid listing (Paypal)

I have the latest version of directory installed here When I try to create a paid listing with payal, it doesnt work; i am prompted to accept terms and I go through the paypal steps and when I finish making payment to paypal it
takes me back to the my listings page and if I try to create a listing I have to start all over again and pay again !!? its impossible to actually create a listing.
Thanks !
