:: MY THOUGHTS for kcb410 ::

From what it sounds, there seems to be some values in the MySql database that is missing. So when (http://www.....com/admin/easypopulate.php) goes to read the stored data, it outputs
"Warning Easy Populate Configuration Missing. Please install your configuration by clicking here:"
By clicking that will run the Sql installation step, where this creates the data stored into your MySql Database. Since you already have a version install you will need to remove the data that was stored when you use the installation of 1.2.5.5. CSV. Now I haven't used Easy Populate to much, but I create php scripts that communicates with a MySql Database. IN ANOTHER WORDS, I'm not sure if Easy Populate has a feature to remove these VALUES out of the database.

:: BUT WHAT I WOULD DO ::
If you are familiar with PhpMyAdmin (LOCATED IN CPANEL), you can go into that back-end and remove the CONFIGURATION KEYS manually.
*I DO NOT RECOMMENDING DOING THIS IF YOU'RE UNFAMILIAR WITH MYSQL DATABASE STRUCTURE*
removing other data can really screw your entire database up.
The process is quite simple:
- To do this, go into your PhpMyAdmin, find the Database you have set for your Zen-Cart Store and CLICK on that name.
- Then find the CONFIGURATION table (if you have a prefix on during the Zencart installation it would like this ex[ pre_configuration ]) and CLICK it.
- then you have to go to the very last configuration keys
NOTE: on mine, it only shows from 1-30, but if you look carefully you can see that there is somewhere around +500 value stored in that one TABLE
- What I do is CLICK( configuration_id ) until the table is ordering the numbers in descending order ex.(500, 499,498,497... etc)
- from here if you look down the (configuration_key) column you will see a bunch of values starting with (EASYPOPULATE_ ... .. .) those will be the ONLY keys you want to delete.
- once deleted you can re-CLICK the button that started all this fuss.

THE "Warning Easy Populate Configuration Missing. Please install your configuration by clicking here:"
:: MY CONCLUSION ::

I'm not sure if that will work for you or not, but those are the steps i would take to a problem such as yours.

I hope this information helps.
