I downloaded 1.3.1 and installing it. I don't know why when I did the update inside the program it downloaded 1.2.1 ?
We had to change the firmware and installation file extensions of the files on the server due to ISP issues. Those "new" extensions are supported in 1.3.1. This affects both Designer installs AND FIRMWARE UPDATES!
Hence, 1.2.1 (and 1.1 and 1.0) "Check for Updates" do not know how to download and install 1.3.1 (or any new firmware file updates!). So if you go through the MENU "Check for Updates" in 1.0 and 1.1, it will say 1.2.1.
This is why we changed the banner on the Start Page to tell you about 1.3, and get you to "Click here to download". That graphic on the Start Page would show up on 1.0, 1.1, 1.2, and even 1.3. If you click THERE, you go to ADC "download" web page, not the internal Designer "Check for Updates" dialog.
Not your fault - it is a bump that we knew would happen, but (hopefully) will only happen this one time. We tried to make the Start Page banner be obvious "click here! click here!" for 1.0, 1.1, and 1.2 users.
If you have 1.3.1, its Check for Updates will work with all the most recent firmware files AND (whenever it becomes available) a new Designer version.
