Cannot add devices any more on my Vera 3

I have latest firmware.
I have problem to add a dimmer. I have added this type of dimmers before. When I press add device I choose the first option and then I get “please wait…”
Nothing happends. I wait and wait
I have rebooted
I have tried from another computer
I have the same problem when pressing on the zWave button on Vera 3 controller. It will not start blink. Second time pressing that button I must wait approx 10 seconds.
What to do???
