Our Roku Premiere just started over heating VERY badly. I've tried at least a dozen times, on 2 phones and a PC to order the free extender on the link provided for that, but once I fill out the form, it will not go through. Please don't send me back to that useless link, just give me a link that works or a number to call to order the extender before this thing burns the house down.
The extender is only available for, and more importantly only useful for, a stick. The Premiere is not a stick and the extender would serve absolutely no purpose. What is the model number shown under Settings->System->About? If your Premiere is less than a year old you may want to start exploring a warranty return.
