USB-eLicenser number already registered by another user

I have 2 USB keys for 2 different versions of CUBASE. One was registered to Steinberg with NO problems and just updated to Pro version from Cubase Element successfully.
The other one got problem when I updated it from Cubase Element to Atris version. The problem was : ( The Licenser assigned to this Activation Code was already registered by another user )
I’m sure my USB key were brand new.
Who can help me solve this problem?
