In the last couple of days, TDS has started downloading the updates every time it's checked, it never says that I already have the most up-to-date definitions anymore. It will do this even if I run the update immediatly after it has downloaded the most recent version. At first I thought maybe it wasn't getting it completely, or saving it correctly, so I downloaded the Radius file and copied it to the installation directory (overwriting the existing one, which it said was the same size and date.) I guess it's not THAT big of a deal, I have task scheduler set to check once a day, and once in a while I'll reboot and it will check automatically when I start it up, so worst case is that it downloads the update twice a day, but it is a bit of an annoyance. Any ideas?
