Thank you for
reaching out on the community and telling us about your issue. Ninja Development Group is a scam. Quicken does cost 49.99 for an annual renewal but that would be directly through quicken not them. If they're asking you to pay money to them do not do so. Since the original 500 was quite a while ago I don't think it would be possible to dispute with your bank but it might be worth a shot. Quicken support included in the product when purchased. I would also advise you to double check which email you're currently signed in under. If you go to
edit -> preferences -> Quicken ID, Sync and alerts do you see your email listed there or is it an unknown one to you?
Please get back to me as soon as you can.
