After rebooting my modem, then rebooting the ROKU, re-adding ACORN TV and checking something on it to see if it works.... it worked.
I too am having the same issue with "exceeding my playback limit." I have read every post in this thread and I have done everything that has been suggested from logging out and logging back in, removing the channel and re-adding it, rebooting my Roku, checking my internet connection, resetting my internet connection, signing into Acorn tv then signing out again... nothing. NOTHING works. I am still getting the message of:
You exceeded your playback limit
I don't really think the problem lies with Acorn TV. I believe it all has to do with some Roku issue. When I first tried to watch something this morning, on Netflix I got the black screen that said something to the effect of me needing to do something with HDMC or some such letters that had me disconnecting the ROKU from my TV then reconnecting it. I'm sure there's at least one person here that can identify with me in reconnecting the ROKU to my TV by having to gather up a mirror and flashlight and being a contortionist to get it back in the correct spot. This particular error occurred with any streaming that I paid for with the exception of YOUTUBE.
After doing that, I was able to bring up Netflix and Britbox to watch something, but when I tried ACORN TV, I began getting this error of exceededing my playback limit.
Nothing suggested in this thread worked for me.
