Nostalgia Pack Beta 1.7.3 updated to version 1.6
I literally removed everything except Optifine and Skinfix. If Singleplayer doesn't work after this I have no idea what to do.
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 (Nostalgia Pack Beta 1.7.3) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Nostalgia Pack Beta 1.7.3 from the list on the left. The launcher will handle everything else!
