Same problem here, tried disabling Windows Defender, Uninstalling and reinstalling on Epic, resetting my internet connection. None of the above worked.

Hi,
this just happened to me after loosing a Standard 2022 ranked match.

I've already tried to re-install the app on iOS but it didn't work.

My connection is fine otherwise I wouldn't be here writing this :)

I tried a few things - restart, reset winsock, dns flush, etc. All my other games are working. Hopefully they are aware of the issue.

Also frustrating that the MTG Arena Status screen makes no reference to this problem and claims that the game is fully operational. As with others game was working fine a few hours ago but then it wouldn't let me start a new game and restarting Arena gave me the above error repeatably.

Did a full reinstall but this did not fix the problem. Clearly I would not have been able to redownload all the game files if there was a problem with my connection.....

I'm getting this error on Windows 10 after the Aug 24th update. I played a couple of games without issues but then after playing the midweek standard 2022 event and getting a win the game crashed and I have been getting an 'error updating data' screen since then. Tried reinstalling, launching from epic games, using VPN, turning the firewall off, updating windows, changing the proxy settings on windows, uninstalling, deleting the registry and reinstalling, deleting the manifest file on the MTG Data folder, running as administrator. Nothing has worked or made any difference.

The same issue here after today's update on PC and restarting the game once.
Android did not work right after update.

Deleting the update manifest file helps on Windows...

Same with Derringer, happened after my first loss of standard 2022 mid week magic(Everything was ok when i won .... ) , i concede, then connection got lost and never came back. Since i can write here you know my internet is OK.

I got the the black screen bug, change my local date, worked for a draft, and now this :
I'm on win 10 pro, last version of the soft is installed+

I updated the game then started up fine on my Android. I won my first match of standard 2022 mid week magic and then got an error message saying Error Updating Data. Now I can't play at all. Tried restarting the game but same message appears.

Same for me, in Windows version... After playing some matches without error.

And delete that file doesn't work

Following the comment by https://feedback.wizards.com/users/5500850649--iln-1-80024 worked for me. The actual file(s) to delete are:

%MTGA_Install_Dir%\MTGA_Data\Downloads\Manifest_*.mtga

e.g.

C:\Program Files\Wizards of the Coast\MTGA\MTGA_Data\Downloads\Manifest_39841652dc16278da5893053aa6d484d.mtga

Also having this problem constantly

This happened on my IPad Pro. I changed the setting of save downloads to the cloud drive to save downloads to the computer (IPad), and I was then able to finish and complete the download

On PC, deleting the old downloads.manifest file worked.

Make sure you've updated your Android Game Client on the App Store to

Check the comments below to make sure you're not running in the IPv4/IPv6 issue mentioned. I detail some steps on how to test this.

Same issues. Anyone able to successfully navigate this on their phone?

I still have the problem and it would be great if it finally worked

I have the same problem: Error updating Data: pleased Check your connection and try again.
and that for almost 2 weeks. Only retry Button

have a Lenovo IdealPad duet Chromebook.

I had to install it several times and it still doesn't work. Everything works fine on the pc, but I could play more often on the chromebook. Please fix and report. Many Thanks
