When you install the Jaman player and start it for the first time, you may see several messages from your firewall software.
Here's what they mean:
1. jaman-
updater.exe (The Jaman installer) - This alert might appear a couple of times as the install is completed.
2. jaman.exe (The Jaman Player) - Allow The Player to connect to the Internet and save/remember the setting if you don't want to see it often when you are doing anything in the Player.
3. jamdownloader.exe (The Jaman Network) - runs even when your player is not open to manage your downloads and any Jaman Network activity, so allow it to connect to the Internet and save/remember the setting if you don't want to see it often even when you don't have the Player running.
