linkpoint nothing past check out page

[jmscoma]

I was able to install linkpoint, remove all errors, upload .pem, and configure admin/modules/payment. Now the problem is when I click on the check out button it goes straight to page not found. I am not sure but from what I hear I believe that I should have buy now buttons from linkpoint at checkout. Also I think that it should be going to account login/register. When I click account login at top of page it also goes to page not found.
