Forza Horizon 4

Hi

Any advice appreciated.

We downloaded Forza Horizon 4 with the free Xbox games pass which was included with our new Xbox box a couple of months ago.

When the free subscription ran out, we unsubscribed from the games pass and we thought that this affected the games that have been downloaded. My son wants to play on it again so have purchased the download version today for £24.99.

When we downloaded it today, we seem to have the demo version. The map only accesses the Lake district to Edinburgh and most other options are disabled. We have tried uninstalling and reinstalling but the same version has opened again.

We are new to the xbox, but haven't had any problems with downloading and installing any other games.

We are still subscribed to the games pass until early July and xbox gold live.

What are we doing wrong!?

Thanks

:)
