I recently got an email saying a project I got is at the risk of being disabled because my payment information is invalid. But the card I got registered for it is the same I've had the last two years, and it's still valid cause I used it yesterday. Also, there is no amount due as far as I can tell. I haven't done anything with the project for 6 month, it's just sitting there. No API usage, nothing.

So I got no idea what to do to address it. I feel my best option is wait for it to get disabled and try to address it afterwards.
