XBOX ERROR 0x00000001

Hello everyone:

I'm getting 0x00000001 error code when I am trying to download Microsoft Flight Simulator 2020 on Xbox App and Microsoft Store for PC.

My account has administrator privileges and my Windows 10 is up to date.

I already tried everything I found on the internet, beginning with wsreset.exe; resetting Xbox, MStore, Gaming Services, App Installer, etc.

I also did some Powershell lines suggested by people for solving this error, but nothing worked for me.
Some things I did too:

- Uninstalled / Re-installed Xbox (Beta) App
- Set my router to multiple DNS Servers

It still does not download the game, since more than a week.

Extra info: Gaming Services is sometimes set to automatic in services and sometimes deactived and I cannot change anything! Maybe that is normal...

I paid for the game and sadly I cannot use it!

Thank you for your time and I hope somebody may and can help me.

:)
