Kymera Map Panel Not Drawing Maps Anymore

I’m working with the Kymera Map Panel module and was able to get it to draw maps for a while using Google. However, after a panning and zooming the panel, it quit drawing the maps. When I place pins, I can pan them like there’s a map there (pins are moving appropriately), but no map is shown. Code I’ve used:

mapPanel = event.source.parent.getComponent('Map Panel')
mapPanel.getTileServer().addLayer(1.0, "s", "google") #Roads

At one point I got an error which included a URL. When I put the URL in, I got a message from Google

Is there a limit to the number of requests Google will allow in a given time period? I do know that they’ve changed their terms of service for the Maps API which requires a paid account to use it at all. Not sure if that’s related though.
