World Corrupted

Just bought the game on my new tablet.
Started Minecraft and pressed New.

Then this message came on screen:
My World is corrupted and can't be started.

I tried withe different names but the same result.
I started with MCPE version 0.9.4 the problem persists in version 0.9.5.

I happend to have version 0.8.0 on an old mobile i copied this version to the new tablet and this version runs fine.
