Update for the Luxus Pro Training videos?

RainbowArtist

When I checked DIM today to see if there were any new DAZ updates, I saw that there was an update for the Luxus Pro Training videos that I bought back when Luxus came out in 2013. I clicked on the info gadget to see what the change was and it said -

Resolved Issues
2015-04-13 - Updated installers.

Since I already installed those files sucessfully a long time ago, is there any point in downloading them again?
If the content hasn't changed [ The current file list seems the same as my DL} then it would be a waste of bandwidth to DL them again? Right?
Thanks.
