title: Quickfix data dictionary problem - repeating group error
body: <p>I am using Quickfix to connect to CTS and I'm having the same exact problem as @Wapiti experienced in this <a href="https://stackoverflow.com/questions/25858091/quickfix-failing-to-read-repeating-group">thread</a>.</p>
  
  <p>Whenever I turn on the DataDictionary and direct to the location of my DataDictionary file, I am unable to Logon to CTS.</p>
  
  <p>Whenever I turn off the DataDictionary, I succeed logging onto CTS but I get the same error that @Wapiti posted:</p>
  
  <p>Event log: Message 3 Rejected: Tag appears more than once:269</p>

  <p>Tag 269 is MDEntryType and it should be a repeating group. I realize my problem probably has to do with the configuration of my data dictionary. I tried switching from 'DataDictionary=...' to 'AppDataDictionary=...' as Steve recommended in the thread linked to above but that didn't resolve the problem.</p>
  
  <p>Any ideas?</p>
