You could check to see if what excel sees as the last used cell is the same as
what you think it should be.
You could reset it by using techniques at Debra Dalgleish's site:

Another technique would be to explicitly set the print range.
File|print area|set print area
And if you have formulas in cells that evaluate to "" so the cell's look empty,
but really aren't, you may want to consider using Data|filter|autofilter. Then
you could show only the non-blank values in a certain column.
