i have not been able to update the game at all the start of the day today Monday the 10th. i've checked verything... it gets to about 40 megabytes says that error updating check connection. connections been fine. checked everything that could be causing issues and nothing. did a uninstall and reinstall to see if it was the program itself and not that still not downloading the full update. its gotten to about 500 and something megabytes total and seems to refuse to go any further then that. i have no idea whats causing it or why. it did a similar thing during the Hobbit pre-release but i was able to fully download that. thats the only thing thats been different between now and the Marvel set that was released months ago. if unable to download may not be able to play mtg arena.
