I'm running SB S&D v 1.6.2. Each time I start the program to do a scan, I have been checking for "updates". Usually, I get a window that tells me updates (Detection Rules at least) are available, and offers numerous "mirror sites" from which to get the download. Today there was an Update Window that showed a green progress bar that very quickly flashed from left to right. At the bottom of the window, the button for "Get Updates" was grayed-out. Then, in a few seconds this whole window closed and nothing else happened -- no updates! Anyone have an idea as to what's going on here?? Thanks.
