Question:"Do not ship this order until it's finished processing"

[madebysir]

hello there.
i am new seller on etsy, and during my first week here i had already 2 orders (!)
i am very happy about this as you can assume, and the product i sell is a calendar which means it should be delivered during these days, before new year.
but i have received an e-mail from etsy, telling me not to ship the order until it's finished processing.
today is the second day after the mail, and i don't know what to do.
any suggestions?
thank you in advance

Hi Serafina Sideri,
My name is Oggie Golev.
I am now in the same situation as you before Christmas.
I opened my shop 3 weeks ago and yesterday was my first sale, today - my second. For both Etsy says to me "Do not ship this order until it’s finished processing".
What did you do to fix it? What happened?
