Bank Reconciliation Error

hello all,

my name is josh and i'm new to this site and i'm having problems with my bank reconciliation.

i'm using microsoft dynamics gp 10.0 sp1, recently i ran an sql script to delete some cheques from the related cm tables for a checkbook. now i'm trying to run the reconcile process but it gives me this error message: "the difference must be zero before you can reconcile this checkbook" eventhough the difference is zero.

can somebody help me on this?

thanks.
