Hi Barb
Do you have a clean backup from a not-too-distant date? If so, you could use GridView to extract the subsequent batches from the recent data, and then use the Import function to post them into the backup. You would also have to re-add any new GL accounts. It's a bit of work but it might not be too bad depending on the volume.
In any case, contacting your dealer is good advice at this point.
