DSF Strings file size?? - SOLVED

Hi,
I downloaded DSF Strings expansion when I initially ordered X2, however I've just noticed that the download link for that same item as included in X2 download files  is reporting itself as 100MB larger - 1.3GB vs 1.4GB.  Wondered if I should be downloading it again??
Actually, I am downloading it again, more to the point is I wonder if I'm wasting my time??
