This issue started in the CTE for 1.2
I had played daily and never been kicked due to this error before trying the CTE and then I ran into it right away.
The patch went live and now I cant get into any game. It loads to 97% (ish) and then I get kicked.
None of the suggested fixes work (all modes selected, cache flushing, reinstalling everything, restarting, etc.).
Whether it is the fault of NWI or EAC it needs to be fixed for lots of us who are facing this issue.
