[Steam] Activate Your Game Error on Launch

Hi, I would like to report a bug.

I downloaded the Dragon Age Inquisition.

Tried to launch it.

Several times failed.

Verified the integrity of the game files.

After a long investigation launched the game (not successfully but at least not without response) with compatibility mode Windows 7 + Admin rights + Turned off Fullscreen Optimalitazion.

Now I am stuck at the "Activate Your Game" form where it asks me for my credentials. Even though I checked, copied, and even typed them correctly, it still tells me, that my email or password is invalid. Even support confirmed that this is a bug and I should report it.

My EA account is connected to my Steam account but this form asks me for an Email or Origin ID. Could it be a problem?

I can provide you with more information if you need it.
