I just had a similar issue with one of our customers, except the DTR was already posted. I was successfully able to post the Daily Sales Reports/Updates when going in a 2nd time, but the first invoice in the batch posted to AR and Inventory twice (did not post to GL twice). The 2nd posting of the invoice showed up as an Adjustment to the original invoice.
I'd suggest copying live company to a backup, post the Invoice Register and scan through some of the first invoices to see if any of them post twice.
