G-sender update

When i open G-sender it always shows new version available but when i click on the download button it looks like its going to download but nothing happens
i am currently on version 1.2.1
how can i get it to update?

The latest mainline release is 1.4.9 and can be found on Github.

It takes a long time to download. It looks like nothing happening, but it should be working. Mine seem to take forever, but it worked. My two cents.
