Hi,
I ran into the same problem and in the end it turned out that the problem was Plugins.Payments.PayPalStandard.Fields.BusinessEmail not matching the PayPal account associated with the token in Plugins.Payments.PayPalStandard.Fields.PDTToken.
This isn't explained and the error message that PayPal is providing is completely misleading; in any case I figured it out after a while: BusinessEmail must match the PayPal account providing the token.
Hope this helps.
This invoice has already been paid. For more information, please contact the merchant. PayPal Standard (Updated and Resolved)

Shorty, and most common mistake =
For PayPal Sandbox is mandatory to use 2x email accounts which is provided from developer.paypal.com >>
Sandbox menu group >> Account.
- one is business which usually ends [email protected]
- another is buyer which usually ends [email protected]
The business account must be saved in nop.admin >> configuration >> payment method >> paypal standard plugin >> and field Bussiness Email. Save it, and that's it!
