Basil, your site location as I recall I checked today and your patch is 7.5.6p1 the current security patch is 7.5.6p2
p2 replaced p1 withing a week or so due to another hole found.
Also I am sure you are aware the patch does not repair any existing damage. So even if you are current if someone has hacked the board prior, there is quite a bit of research to do for cleanup.
