Steinberg eLicensor- - All licences disappear suddenly

Hello,
I use my eLicensor USB with quite a few plug ins and apps like:

Cubase 6.5
Wavelab Essential
Vengeance plug ins
Nexus 2

But today I turned on my Mac I normally worked on project in cubase, but after saving the project and loading different DAW and back Cubase it shows me I have no licence key, so I opened elicensor license software and run maintenance, but in the software no licences are on my key anymore.

How it is possible? How can I restore my licences to the usb-key?

I was quite suprised, that there is no online license overview like with iLock or Waves, where you can see your licences online and test if it is just a problem of your HW key or if it is a problem of your account.

How can I test it? Which steps can I do for recovering my licences back?
I cannot imagine to contact all the companies separately and ask everyone for the license recover.
In this way it is quite unuseful.

Thanks for help!
