Synchronize doesn't seem to work

In our home we have 3 PC’s and noticed that the synchronize doesn’t seem to work. Get a failed message when ever Sync Now is used. And auto sync doesn’t work.

Was using another method to block all SPAM before which worked fine for a few years, but it takes a bit to set it up.

Over all I think Comodo AntiSpam is pretty good software! Easy to set up.
