Don't assume the issue is related to your previous listing in NY. Airbnb looks at the legal address of the property to determine if there are any registration/licensing requirements to list on the platform. Have you checked the local laws in Maine where the new property is located and determined if there are any registration/licensing requirements? You may actually need to also have a license/registration number for the property in Maine. What city/county in Maine is the property located?
A quick internet search shows several cities in Maine with licensing requirements for STRs:

Taxes
You might also want to check if the local city/county imposes an Occupancy Tax that you are required to collect and remit. Airbnb doesn't always collect all the required taxes for you. Looks like they only collect the 9% state sales tax.

The best time to contact CS appears to be after 7pm...you are more likely to get a US-Based agent.
