The answer is simple ..........Its new version is out...........Ares 1.9.4. So, the old versions won't work.
This is the biggest drawback of a p2p sharing software, when a new version is launched the old one just stops working and most people end up adjusting their proxy settings to know what's wrong!
Ares is an open source too, so updates are more frequent..
So, download the latest version .
