I don’t think so. Make sure all you data is in one database.

Yes, it means you have some rows or columns with empty data in them, sort of like leftover from some previous file. So make sure there are no blank rows or columns within the databases occupied data. Also to insure there’s no data in the columns and rows outside the boundaries of the data, I usually select many blank columns to the right of the filled in data and hit delete. Same thing on the rows below the filled in data. Hope this helps. Let me know if it works.
