Error loading demo database

[erickge]

I am new to nuBuilder and decided to try and load the demo.
I used nuAdmin to create a site called sample
I logged on to the sample site
On the Home screen I selected Database
I went to the databases tab and selected sample
Went to import tab and chose nubuilderprodemo.sql which I had downloaded earlier. Pressed Go
it spun for a while and I got this


Error
SQL query:

--
-- Dumping data for table `zzzsys_access_level`

INSERT INTO `zzzsys_access_level` ( `zzzsys_access_level_id` , `sal_code` , `sal_description` , `sal_zzzsys_form_id` , `zzzsys_access_level_log_added_at` , `zzzsys_access_level_log_added_by` , `zzzsys_access_level_log_changed_at` , `zzzsys_access_level_log_changed_by` , `zzzsys_access_level_log_viewed_at` , `zzzsys_access_level_log_viewed_by` )

);

MySQL said: Documentation

#1062 - Duplicate entry '54ab7ad219b4869' for key 'PRIMARY'

What did I do wrong and how do I fix it. Thanks!
