It sounds like you may have created a Roku account that isn't located in your current region. If channels in your region are not available, it may indicate that your device is linked to an account that was created in a different region where that channel may not be offered by the channel provider. You'll want to make sure that you are using an internet connection located in the correct region when creating your account. You can check your IP address' reported location by visiting www.whatismyip.com - If you see an issue, you'll need to contact your ISP to help resolve any issue.
We would recommend creating a new Roku account in your region. For more information about how to create a new account, visit our Support page here: How do I create a Roku® account? Once your new account is set up, try to perform a factory reset on your device and link it to your new account.
Follow the steps below from your Roku device to perform a factory reset.
Press the Home button home on your Roku remote.
Scroll up or down and select Settings.
Select Advanced system settings.
Select Factory reset.
Select Factory reset everything and follow the on-screen instructions.
Otherwise, please reach out to our accounts team directly. They can be contacted at http://support.roku.com/contactus. Choose the option for "Accounts and Billing." This should resolve the error you are seeing.
Please try doing this and see if it helps with what you're experiencing.
