Hi Maria,
With the Substance account you posted a message with (and with which you downloaded the "Chesterfield" material) you don't seem to have a subscription.
From what I can see in your account you started a trial version of Substance Designer.
The 30 download points per month are only included in the subscription, they are not included in the standalone version of the tools or in their trial versions.
If you have indeed purchased a subscription, would it be possible that it was with another Substance account? That would explain why you don't have a subscription and the 30 download points in your account.
