PayPal recurring must be 1-90 days? (instead of 1-year)

Our first customer order on a new product just got rejected by PayPal with the message:

Interval must be 1-90 Days

In AMember Pro, we're using the Standard PayPal plug-in and have this product set to a 1 Year "Duration" with "Recurring Billing" checked on (no trial period).

Called PayPal and they confirmed that a 1-year recurring subscription is valid with our Business account.

Any suggestions?

Thanks
Rick

Attach a screenshot of your product settings.

The problem turned out to be I accidentally had a value of "0" for the free trial duration instead of blank.

Thanks for the response.
