Linda,
I'm sorry to hear this! Are you receiving any error messages at all when you are trying to download?
You can try resetting the smart hub here's a link to walk you through those steps:

Can you also provide us with the model number?

Went to the app area on TV to download some apps - but they won't download - My TV is registered on Samsung site and I do have an internet connection - am I missing something else that I need to do? Thanks!
