In order to get around this problem, you will first have to configure your router with Unlocator DNS. Then once your setup has been verified at http://unlocator.com/account/login/index you can now visit http://owner.roku.com and create your account.
If you choose your credit card as your payment method, fill out all info with US info and once you have to input your zip-code simply make sure that the zip-code has 5 digits and that the last are included in your real zip-code. Lets say my real zip-code is 1600 I will then put 01600.
Now you have a US based Roku account and you can add the channels you need to your account. Then proceed to do a normal setup of the Roku box.
If you have already setup your Roku box with a non US account you will have to reset the Roku to factory settings.
From the Roku home screen, select settings > factory reset, and follow the on-screen instructions.
ImportantFirst step of troubleshooting should always be to restart device(s) and router. Then check your account status in your account home. You should always see 3 green check marks if the device you are using to visit the account home is set up correctly.
