Do you already have the database structure in your online (go-daddy) database as set up during the Powerstore install?
Not sure what type of testing server you're using, or how you are administering your local mySql, but whether via phpMyAdmin or some other mySql manager, when you do the export from the local database you should have the option to export just the data to a sql file (deselect everything else from the export options - i.e structure, and even the extra data options) .
Then try importing the sql file into the database.
None of this based on experience or even hearsay, - just wondered if that would make a difference.
