Starting from April 22nd and planning ahead fro the new version 4, we had to make some changes in our Update Servers.
As a matter of fact, to continue getting new updates, you will be required to install a Bundle (attached to this post) in order to update the path to future MT updates.
This patch (bundle) is needed if you want to get any other hotfix for your MT version 3.X
Remember to unzip the file before upload to your MT and wait until the web-browser restarts by itself.
the new version will show:version 3.3.9 release date on April 22nd 2016 01
