Hello I have an active paid subscription, but when I try to change lead time it says Free accounts only allowed one...

Hello Thanh,

Thank you for your question about your subscription. We credited it as soon as I saw this yesterday, so I'm writing to close the thread.

Our PayPal "IPN" payment notifications didn't register the payment, so I just updated you manually.

Welcome to Premium! I hope I replied to your satisfaction. Please let me know if I can help further.
