windows crash with wamp (no replies)

I had win7 with an earlier Wamp and Wordpress. So the PC crashed....totaly
Luckily I had a backup sql file for my local website
Now I have installed the latest Wamp on Win10 and got the green icon.
So I made a PHP databas.
Then I instaled Wordpress and named the folder as the databas. Set up the WP config file and connected to the database.

Then I tried to import the securityfile but only get an error #1062 - Duplicate entry '1' for key 'PRIMARY'

I am not sure what to do. Hope for help..
