I have seen that before Jay,
each version of Sentinel has a different "latest" update date.
Not usually, no. And the thread linked from June has nothing to do with this.
As I said, I updated both versions on Monday on my laptop and both had 7/13 database dates.
I didn't bother updating my desktop until I saw this thread, and when I tried it tonight, the HP1 software got a 7/13 update, but the x36 software said that its existing 7/6 database was the most current.
Some time in between Monday (or more likely Tuesday, considering the post from mule1075 above) and today, it appears the 7/13 database went AWOL from the x36 ftp site.
