Back to My Mac

Hello All

I'm trying to use this feature. I feel like I have it set up in iCloud correctly and I THINK I have the sharing preferences set up.

When I look in the finder window I can see both my iMac from my MacBook Air and vice versa.

However when I go to connect this is where I run into the trouble.

I'd like to connect using Apple ID...how when I click connect it just "vibrates' suggesting it won't connect(It does not ask for a password). Both computers are connected to my apple id. Calendar/Contacts etc are shared no problem .

I try connecting as a registered user and that does not work.

I try even as a guest and it says "Access to your account on the server(my computer name) has been denied. Contact your system administrator for more information.

Any ideas whats up?

For what its worth my iMac is "hard wired" and the MacBook Air is connected through WiFi.

Any help would be appreciated
Cheers

Anyone have any idea what is up?

(should I just use another service?)
