Paying resort balance 45 days out

[WDWRookie2009]

Hello everyone !
In previous years I had to pay remaining balance of our package 45 days out from our first night. We will be there June 16th but it says my balance must be paid by May 17th. Everything I have looked up still shows 45 days out. Did I miss something ?
