I'm sure there's a better way and maybe Jason or Ray will chime in and correct me. But what I would do off hand is create a temp folder on your server (name it DELETE ME or something you'll know to get rid of when your done) and then copy all of your powerstore files (from your original zip) into it and run the install again. This will create the tables in the DB for you. Then simply delete that folder. The data won't be there of course but you'll have the table and structure.
