The OriginsRO Launcher
Now that you've got all the boring signing up stuff over with, lets get to actually playing the game!
Navigate to your freshly installed OriginsRO folder, and double click OriginsroLauncher.
And there it is!
From here just enter your master account details and press the login button.
After that, there are a couple of things you can do.
The top button displays a list of all your registered game accounts, just click on it, and select one in the drop-down menu to start playing.
The second button marked "Manage Game Accounts", lets you manage a few things related to your game accounts, namely setting a default game account, or show specific game accounts in the CP.
The "Play as a guest" button, lets you log in on guest access enabled game accounts your friends might have given you, just click on it and then enter its login details.
The "Replay theater" button launches the client into Replay Playback mode, and lets you play recordings you might have made in-game with the replay recording system.
And finally, the "Settings" button, lets you edit various preferences related to video/sound and game options, as shown below:
And those are pretty much all the important bits to remember, good luck, and have fun!
