Hi Vickie
This is the response I have had from Craftsy they have been extremely helpful
Cheers Shareen

Thanks for the response, I hope you're doing well! Certainly a device purchased in May of this year should be able to play our courses. It is running Android Jelly Bean operating system which should be able to handle our courses. What browser do you typically use when you're watching our courses? Do you use Google Chrome? If you could do me a favor and try clearing your cache on your device that'd be greatly appreciated. If you're unsure how to this, I have provided you with a link below that will assist you:

How to Clear Cookies, Cache, and History from Android Phones

After, you've cleared your cache please go ahead and try viewing your course. Hopefully, this should resolve this issue and you should be back enjoying your courses. If you have any further questions please just let me know, I'd love to help!
