Is this problem regarding Quik Link for Excel, or is it for Quik Reports?

If Quik Link, does your reading of records 'overwrite' existing lines on your spreadsheet? It's possible that the number of lines being read has changed, and therefore not all lines are being overwritten. I would suggest attempting to re-read your values to a blank sheet to make sure that your lines are correct.

Also try recreating the link, or perhaps even the spreadsheet in case something became corrupted with your existing spreadsheet. I can't say why this would be happening without additional information.
