Need help with Channel

I was having issues with the Roku Preview channel. everytime i would choose it, it would go back to the home page. So i thought i would remove the channel and re-add it back. But i cant find out how to add the preview channel back. Any ideas?

Try this link to add the preview channel :
https://owner.roku.com/add/tablopreview

i tried, it didnt show back up.

It will have probably shown up by the time you read this as roku usually updates itself overnight, but if not go to your settings on the Roku and force a system update. This will update and add any pending channels to your roku.

at work so i will check tonight. But i had the Roku do a system update and it didnt bring it back.
