Minecraft Xbox 360 edition, can't redownload

This question may seem redundant, but are you trying to install the game on the Xbox 360 right? The reason for this being is often times people get a little confused as to why Minecraft has so many versions for example on Xbox alone there are three different
versions: Xbox 360 (only downloadable and playable on the Xbox 360), the Xbox One Edition (a port of the Xbox 360 edition), and the Windows 10 edition now commonly referred to as Minecraft Bedrock or just simply "Minecraft."

If you're on the Xbox 360 and it is making you pay for the game, even though you're under the impression you bought the game a few years ago, the likely scenario is that the game wasn't purchased under your account on that console. Since you mentioned having
a sibling, the chances are the game could be downloaded through their account. You need to be logged into the account that purchased the game. Purchase history can be found at http://account.microsoft.com/billing/orders

Hmm, you maybe have spawned in a cave. Try making a new world and see if the problem is fixed. Or, redownload Minecraft Xbox 360 Edition

So I think this page lays out what you need.

The problem is that you can't transfer a world directly from Xbox 360 Minecraft to the latest Bedrock edition of Minecraft. You need to transfer it through the Minecraft: Xbox One edition first.

The
details are laid out here

Basically you'll go from Minecraft: 360 Edition > Minecraft: Xbox One Edition > Minecraft (bedrock)

Let us know if you have problems or questions.

The Xbox 360 version of Minecraft is not backwards compatible on the Xbox One.

If you had owned Minecraft 360 digitally, you could have had the benefit of getting the "Xbox One Edition" at a reduced price, and if you owned the Xbox One Edition, you could then get the "Minecraft" without "Xbox One Edition" on the Xbox One for free.

However, these offers have all now expired, and the only way to get Minecraft on your Xbox One is to buy the game again.

Be aware: You can't import your Xbox 360 worlds in the newer Xbox One Minecraft!

If getting your Xbox 360 world over is important for you, you need to find someone with "Minecraft Xbox One Edition" and import it to that game first. Then import that world into "Minecraft" on the Xbox One.

Back then when the Xbox One Edition (the Minecraft with the "Xbox One Edition" in the name, not the new "Minecraft" for Xbox One) was released, there was a short time, where you could buy "Minecraft Xbox One Edition" for a reduced price, if you owned the
original Xbox 360 Minecraft digitally.

Xbox 360 Minecraft and Xbox One Edition Minecraft are two different things. Like having a vinyl record of a music album and then having to buy a CD of the same album. Or having a DVD of a movie, and having to pay for the BluRay version of the movie.

However, the Xbox One Edition can't be bought nowadays anymore. Have you had the Xbox One Edition digitally, you would get the "Minecraft" (without the "Xbox One Edition" in the name) for free.

You can however transfer your Xbox 360 worlds to the Xbox One, if you somehow got hold of the "Xbox One Edition" before it was replaced by the new "Minecraft".

To do that, start your Xbox 360 Minecraft and make sure it's on the latest version. Then use the menu entry to upload your world to the online cloud.

Now start up Minecraft Xbox One Edition and import your world.

With your world in the Xbox One Edition, you can then start the "new" Minecraft on the Xbox One, and import your world from the Xbox One Edition to the new Minecraft.
