Adobe Digital Edition V3.0.1.91394

I just downloaded Adobe Digital Edition V 3, (I need this version for my E-reader).

I have an Adobe ID.

When I try to activate my PC, I get following error:

Activation Server error

code : E_AUTH_NOT_READY

I'm not able to authorize my PC, I'm able to log on to my Adobe ID.

Please advise what to do?
