I didn't perform the conversion. Our sales support did, and it's complete. I don't understand what could have happened, but I'm not going to have him re-convert as we've already re-entered the payment information to those where it was necessary to do so and posted them. I have the original printed invoices which clearly show that payment was applied - then, after the conversion when we went into the batch, those details were no longer there. Could have been a blip on our end. However, it's fixed at our office so I don't think re-converting would be prudent.
