It happens every single bloody day.
At the beginning iTunes works fine. I can see my 'Recommendation' and 'Connect' in the 'For you' tab. However from time to time the following error message appears. It can happen multiple times in a day.
How can I recover from it short of restarting itune? The 'OK' did nothing.

I had the same problem the other day.
I signed out from my account (go to Account -> Sign out...) and then I quit iTunes. I signed in after relaunching and everything seems to be working. It has been working fine for the last two days.
