Thank you! This formula worked. When I called TWC cs when problem started, they did not have an answer. I was told by one person that I would have to upgrade from roku 2 to roku 3. I am glad you had this solution online. It saved me $.
I have a Roku LT and I also had problems getting it to work. What I had to do was uninstall the TWC channel and then I restarted the roku. Then I followed the steps to go into developer mode. Then I followed the same steps to exit developer mode. After I did all this I reinstalled the TWC channel and it worked after that.
