Zyxel Multi APP - second location

Hi,

i try to add a second location to my Zxyel Multi App.

Finding and configuration of the new Multi X works fine, but after this there is always an error "Setuperror" and Multy can´t be activated.

The new WLAN is working after this, but i can´t see the new Router in the App and i can´t change the destinations ? Already tried a lot of resets and a second router. Still same Problem.

Any ideas ?

Thanks

Oliver
