Thanks! I am trying to help the best I can not knowing my head from a hole in the ground when it comes to coding!
I did it a couple of ways:
1. Kept the code changes from the last post in admin/easypopulate_4.php, then I changed line 990 in admin/includes/functions/extra_functions/easypopulate_4_functions.php with the code you just provided and got EP4 FATAL ERROR: No default language set. Table: languages Code: en is set
2. Then I reverted admin/easypopulate_4.php to its original code and I changed line 990 in admin/includes/functions/extra_functions/easypopulate_4_functions.php with the code you provided and now get EP4 FATAL ERROR: No default language set.
