Updating Quickbooks pricing

We create our prices using Microsoft Access. Access provides a "dump" of all of the items and their new pricing. We were able to convert the file with Saasant updating a file exported from Quickbooks and import it back into Quickbooks, thus updating prices. Something has quit working in the process and we need to update prices urgently.

We need someone with knowledge of all 3 of these programs - Quickbooks for Manufacturing, Saasant, and Access to help us. We also use a dump file from Access to update prices on our websites and need help with that.
