I did find this issue as resolved for a different device and there was an administrator comment to open a new ticket for other devices. I also had to choose version 0.11.2, but the version I have installed is 0.11.1.

My daughter has a Boost ZTE Warp Sequent N861.7. We recently bought Minecraft: PE and when we try to create a world it says:

"<World Name>" can't be opened. Permission Denied

The only option is to press Ok and return to title screen.

If this problem cannot be resolved in a timely manner, how would I go about getting a refund for my purchase?

Thank you.
