MCPE Crashes when you open the app

Did you recently leave beta testing and install 0.15.7? If so, please try the following:

1. uninstall MCPE

2. make a copy of your MinecraftWorlds folder (to save worlds)

3. delete the com.mojang folder (to clean out all old files)

4. reinstall MCPE

5. start MCPE

6. if MCPE starts fine, close it and try restoring your MinecraftWorlds folder

7. start MPCE
   if MCPE then crashes, make sure you remove all worlds from your MinecraftWorlds folder that were played while beta testing 0.16 (they won't be compatible with 0.15.7, so you'll need to restore them from a previous backup)

I did

I already read that one

I'll try that

Okay it worked, thank you
