My account on thinkific is cookingasmedicine.thinkific.com When I go to the "course" and click on a video whether in my class or one I am taking, the videos will NOT play. I have been talking with Thinkific and we've gone through all the videos of yours and theirs - the settings, checked my updates and nothing works. I have no trouble on my laptop or my Iphone using firefox on laptop just on my desktop LENOVO. I checked my set up that is on the laptop and made it exactly the same on my desktop but STILL to no avail. The videos will simply NOT play! Would you please help me? I have Windows 10 and currently have auto updates so I am up to date with your updates. I just can't imagine what it could be that's stopping the videos from playing? They played perfectly for three years! I have not put any new apps or programs on my computer either. Thank you, Claire
