apple tv wont recognise my apple ID email address and password
I recently changed my Apple ID and am using the same one for iCloud as well .Now whilst iTunes store is recognised on my Apple tv the same is not so for iCloud .Its telling me - "either account name or password is incorrect " and yet I am using exactly the same ones .
I changed my Apple ID because I will be using a different ISP in the near future so decided to use a Gmail account I have instead.
Can someone suggest were i might be going wrong?
Thanks
AppleTV 2, OS X Yosemite (10.10.1), Mini iPad
