I am in the final prep of moving up to 2.0x from 1.5.7c. I have everything documented and working except for payment modules as I am working on a local server and can't really test those. I just installed OPC and got this screen when I tried to checkout.

Is this a result of me not having Square or Paypal (our normal payment methods) installed? Or did I mess up somewhere? This is actually the second time I have tried this and I have full backups just in case.
