We have recently upgraded from SDL Tridion 2011 SP1 to SDL Tridion 2013 SP1. Everything seems to be working fine except creating/opening mailings. When trying to create a mailing we are getting the following error:
Could not load file or assembly 'Tridion.OutboundEmail.Templating, Version=188.8.131.522, Culture=neutral, PublicKeyToken=ddfc895746e5ee6b' or one of its dependencies. The system cannot find the file specified. Do you want to close this window?
We are using Oracle 11g R2 (184.108.40.206) as the CMS DB and Oracle 12c (220.127.116.11) client on the CMS server.
