Today, Zhuowei Zhang, the creator of BlockLauncher for Minecraft Pocket Edition, announced that updates for BlockLauncher are experiencing a slight delay. The new version of BlockLauncher is currently functional within the game; however, unfortunately, mods are not supported at this time (an error message appears).
While Zhuowei Zhang works on resolving this issue, you can continue to enjoy Minecraft PE using BlockLauncher 1.10.5. (We do not recommend the new version 1.11 just yet!)
Sorry about delay in updating BlockLauncher: currently it goes ingame, but most ModPE script methods do not work. https://t.co/wBArbX1rg7— Zhuowei Zhang (@zhuowei) November 22, 2015
