Any OLC gurus? HELP PLEASE!

Hi,
I flew a 300K flight yesterday (Friday) that I tried to submit to the OLC.
They keep denying my flight. I will give some facts below so we don't have to
go through them. If you think you may know the answer, I will E-Mail you the
flight and let you have a look.
1. Yes, it is a Cambridge
2. Yes, I did go into DOS and fix it
3. Yes, all my information is correct on the submission form.
4. I have had no problems submitting in the past, the only difference with
this flight was that I actually declaired it before hand.

Any help would be appriciated, THANK YOU!
