CRE Loaded 6.3 Onepage Checkout Shipping Fix

I have CRE Loaded 6.3.1 Pro B2B and have just become aware that there is a minor issue with the one page checkout module. If no payment module is selected a javascript error message is displayed. However, if no shipping is selected the software still allows checkout. I believe this issue has been fixed in 6.3.3 so it should be an easy fix for anyone who has this version. I simply need to be sent the updated files.
