I'm upgrading from 1.3.9h and I'm happy to loose customisations as the site needs an overhaul but I do want to loose the database.

-I created a new database in cPanel.
-Exported old database and imported into new database with phpMyadmin.
- Created a new folder on server and uploaded zecart 1.5.0
- ran zc_install and put in details for the new database, using same database username and password as old site.
- went through the rest of the installation process.
- opened admin section on new site.
- database is empty.

I checked the database and it's an exact copy of the old one.
I checked the config.php files and the database prefix (none) and database username and password are identical between the new and old sites. Only difference is the database name.

The instructions say 'choose upgrade database' but I'm never given the option.

What gives?
