Using: CommandLine Scanner 184.108.40.206 a2cmd.exe /update does not complaint about anything, but every time we run it we get the "0 KB" donwloads. By checking the "Signatures" folder, we find out that there are no new signatures since we installed the program (about a week ago). The only file whose date is recent is the one called "a2vers.dat". I do not think this is normal. When we used version 5.x, there wasn't a single day without updates; so I think that a2cmd is somehow missconfigured and decides (wrongly) not to update itself.
