Problem restoring Sql database – newbie

I am trying to restore a WordPress Blog backup to a new host. I had a plugin which saved a complete backup to Dropbox on a regular basis. I am glad I had this as I corrupted my blog when I tried to upgrade to the latest WordPress 3.5 on my previous host.

I am having a problem trying to restore my Sql database to my new hosting service (Bluehost)

The plugin I used to create my backup is “Wordpress Backup to Dropbox”.

I have installed a clean WordPress (3.5) on my new host. Using Phpmyadmin I made sure my tables are all empty. Once I did that I try to import my Backup database file.

I get the following error message and I don’t know what to do to make it work.
“ MySQL said:

#1050 – Table ‘truewp_users’ already exists”

Hopefully someone will be able to point me in the right direction. Thank-you in anticipation.
