Urgent Help-485 submitted on Sep 28th

Urgent help:

485 submitted on Sept 28th. Got Notice of Receipt on Last Thursday. However, received a Reject of Application on Friday (the whole 485 package was sent back:), bacause the Check was not properly written.

Ask: can I still resubmit my 485 again with a new check? Will they still take it after Oct. 1st, considering I have the original receipt of notice?

Your quick response is highly appreciated!!!!
