'Server Error in /ecp Application' after Exchange 2013 CU9 Update
Installed CU9 update and it failed. Now I can't get into the Administrative Center.  I get a page that says "Server Error /ecp Application.  It highlights the following line in the web.config file: "<add assembly="Microsoft.Exchange.Clients.Strings, Version=15.0.0.0, Culture=neutral, publicKeyToken=31bf3856ad364e35" />".
