Why sudden can’t watch without valid days?

Why sudden can’t watch without valid days?

Even though I don’t change the box and the subscription is within the validity period. The box shows valid days “0”.

It shows the codes already be used when I enter.

The reason is that you have switched  the internet from lan to wifi or wifi to lan and the used ID be changed.

How to sort it out?

1. You can fix by yourself. Steps as below:
Uninstall the apk first, then switch wifi to cable or cable to wifi, then connect VPN, and go to iviewhdtv.com to download the apk, then enter the code.
2. Provide us the order number & code & user ID, we fix.
