Crashes with Wifi

Sure, its a great game, though I prefer playing on pc. Now my friend and I wanted to play together and she only had it on her phone. It didnt work, so we didnt try. Now this time we decided to try again. It wont even load when I turn on wifi, so I turned off my wifi to try again. It loaded. I try to create a world again, turning on wifi. It REFUSES TO LOAD! Please fix this.
