SCP Trial Account: Our records indicate that your user does not have any accounts in this region

I've tried to register a trial account. The message was I'm already registered.

When I access https://account.hanatrial.ondemand.com/

the authentification works with my S-User certificate. Unfortunately no accounts are available. SAP Support called and recommended to create a question here.

They told me that I'm authenticated with my S-User but for the trial a suffix "trial" is added to the user.

Has anybody had the same issue and could solve it?

Thanks.
