If you have a "Downloading world" text when you enter the Aether and its not loading, close the game and relaunch it. I hope this helped you :)
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (SAO Sword Art Online Minecraft) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select SAO Sword Art Online Minecraft from the list on the left. The launcher will handle everything else!
