Path problem in civicrm under wordpress
To the best of my knowledge, CiviCRM does not work if WordPress is installed in its own directory rather than the default location.  I have not tested this recently, but 


I know it did not work in the initial versions of CiviCRM for WordPress,
I haven't heard about any change to this, and
I haven't had any reason to have WordPress in its own directory.


Notes in CRM-16421 also indicate that it's still an issue as of 4.6.

My advice is to get WordPress back out of its own directory and try again.  It may not be your preference, but it's what works.
