If you have connected your PayPal a year ago, the pay key may have expired as PayPal allow us to use it for max 1 year. Please disconnect and reconnect your PayPal in your Subliminator payment setings.
You can do so by going to Subliminator → Billing → Billing Methods → Remove current PayPal billing method and re-add it again.
