mass email sender database

My client wants the mass email sender plugin. They have their membership with you as do I.
I enabled it, but of all the luck the database was not created. This network does not have a MultiDB.
I find the sql.txt, but it says create wp_mass_mailer
Am I supposed to change the wp to our prefix before running this??
I read your instruction, and it is not mentioned. I need verification on this.
Please let me know.
