I heard some users and modders are having issues with new launcher. This guide how I fixed the new launcher, follow the guide below.
Other TWW2 Guides:
Fix the Launcher
- Do right click at name of this game in list and select properties.
- Go to BETA tab and select launcher_release_candidate.
- Then close the window and wait for download to complete, then run the game, select some mods are updated and enable them.
- The mod worked, I'm using New World Versus Old World - UI Overhaul.
- Then exit the game and repeat the first step, now select none in BETA tab and close the window.
- Re-enable the mods again in new launcher.
- It should work after all as it's in my game. (I assume they changed settings each you change launcher, not sure how).
