Logitech autotoggle and GS:E not working after 8.1 Patch?

I have been using Logitech Gaming Software for my mouse to toggle fire the GS:E macro when I press a mouse key since a year almost now.
But, ever since 8.1 update, the button no longer fires the macro? I didn’t change anything and even updated the GS:E addon.
Anyone know what’s the problem?

I fixed this issue. For people finding this thread using Google.
Basically Logitech Gaming Software doesn’t check for update or autoupdate.
I just had to download the latest version.
