There was a new update to mtg arena yesterday and ever since then I haven’t been able to get back onto arena.
I had trouble after the last update and after following the advice in this post:
I was able to get back up and running.
However now when I try and run the MTGA.exe it tells me that I need to run the MTGALauncher.exe, which deleted itself and had a message saying that it couldn’t finish.
I reinstalled it yesterday, and have tired deleting the MTGA directory and running the installer and still have the same problem.
The post from bascobug solved my problem, but I had to do a complete reinstall for it to work
