Please make a backup of the data that you feel isn't reporting the correct numbers, and send it too me with PDF's of some of the reports that show the transactions being posted properly but where the amounts are now "wrong". In the e-mail describe why you thing the amounts are "wrong", so that we can try and piece together what is going on.
Presumably the discrepancy you are talking about exists in the standard Trial Balance and GL Detail listing reports - we're not talking about a financial statement where just a formula or account range might be wrong.
Before deciding the best course of action, we should take a look at the current state of the Ledger. Have you considered posting a further set of adjusting journal entries to make the figures "right"?
