Samsung Integration stopped working

Hi

I updated to latest release, which includes supprot for the latest generation of TVs

After update, i added the TV and it worked! which is great! i could control it etc and it worked well

Today, i noticed ive lot control of it, When i viewed the integration i noticed the TV was missing, so i removed the integration and re added the TV

It tells me it added ok, but clicking the integration again does not list the TV anymore.

I now notice on my tv a box keeps coming up (like it did back when i first added) to accept control of the TV, however no matter what i do, pressing allow, withing 30 seconds or so it just comes back

HAS also keeps detecting it as a new device wanting me to add it
