Is this the same thread for 1.2.5.5 that uses a csv? I just installed this but am getting the same error.

EASYPOPULATE_MSGSTACK_INSTALL_KEYS_FAIL

I also had this error in 1.2.4.5 --

Is there something additional for the install I am missing that's obvious besides just copying in easypopulate.php into the admin folder? This seems like such a great product if I can get it working...
