Tried your link out of curiousity earlier,(I have had no bother with this download). The link went to a page showing that the page requested was not available and has possibly been moved. However I received notification this morning that 811493 was available. I went to the update page, and although as I said I already have this updtae, it did download and install, so I assume that I now have the corrected version. I now note that your posting has been modified and the link no longer shows.
If anyone who has had problems with the update goes to Windows update, they should also be offered the modified version.
