After using Acrobat Distiller object, certain formatting causes error
 

Strange situation - I have a routine that creates adobe
files and uses the CDO library to email them out. After
running this procedure, certain formatting functions, like:

Like the following:

wksFin.Range(wksFin.Cells(FIN_DATE_ROW, FIN_X_COL),
wksFin.Cells(FIN_DATE_ROW, FIN_X_COL)).NumberFormat
= "m/d/yy"


This causes the error
"Unable to set the number format property..."

Routine is usually fine - it's only after running a
certain piece of code totally unrelated that the sheet
starts giving all kinds of errors then crashes.
