Excel 2007 unwanted array inserts itself at startup
 

I downloaded to my desktop, a sample of work from a coder. It was an array,
10 cells by 10 cells, with a number in each cell; there is a column of "1's",
"2's", etc. to "10"s."

When starting any worksheet, the array inserts itself on top of the existing
data. It eliminates the existing data. When I delete the cells affected by
the array, the original data is also eliminated.

I cannot create an new worksheet without this array inserting itself and I
cannot use existing worksheets because they get destroyed.

I would appreciate a way to eliminate this code that
