Whenever I d/l something it's run through my NAV by default & if I have anything the least bit suspicious i'll run AVP just to be certain. The patch came through clean on both counts. However one thought I did have regarding the "send back" is that it maybe an attempt by Curious Labs to curtail some of the myriad warez copies of Poser that are floating around out there. This would be one of the reasons no one was informed since all the "warez kitties" would have to do is not install the patch to avoid detection.
