ATV1 after boot "iTunes 9.0.2. recommended"

After starting ATV1 i get a message that i have to use iTunes 9.0.2.

But i’ve already iTunes 10.xy

I have to press “ok”, otherwise no sync is available. SO there is no automatic sync anymore.

I’ve recently updated some plugins (remember XMBC, Nitro, Last FM,…)


Any hints?
