Could Not Reproduce Game suddenly stopped working - Fresh Install Causes Same Error

[LuckyReden]

I'm guessing its something to do with my computer, but I haven't run any updates or installed any new software in the past month.

Every time I run the program I get the following:
We apologize for the inconvenience, but Magic Online has encountered a problem. Magic Online may need to restart before you can continue playing.

I uninstalled the game and deleted all local content (as far as I'm aware, but I'd guess I did not), fresh installations create the same error.

What do I need to do to fix?

When uninstalling, did you follow the instructions to run ClearCache, delete the 2.0 folder and reboot before re-installing?

This will usually fix most problems, unless it's a connectivity issue. Using a U.S. VPN usually helps with those issues.
