Hi,
To make things clear for everybody:
- if you already have Substance Live in monthly payment, it's not possible to deduct anything from the remaining amount to pay.
- if you don't have Substance Live and if you purchase a full license, then you can subscribe to Substance Live and pay only the difference
So for example if you purchase Substance Painter on Steam, you can upgrade to Substance Live for only $150 (or 8 monthly payment of $19.90) and get B2M3 and SD5. This is a NEW Substance live license.
If you already have Substance Live and decides to purchase Substance Painter, then you would end with 2 licenses of Substance Painter.
Regarding asking for the password: this was only to visualize what you had on your screen (exactly like you) to be able to guide you during the purchase process, not to manage your account.
Cheers,
Nicolas
