Cannot install demo site happylager I have trouble installing the demo site 'happylager'. 

Windows 8.1 
WAMP 3.0.4 - MySQL 5.7.11 - PHP 5.6.19 - Apache 2.4.18

I follow the instructions from https://github.com/pixelandtonic/HappyLager and when I import the .sql file I get this error message.



When I head back to happylager.dev/admin I get the installation screen, not the login screen as it is described in the repo. What do you think is the problem? 

Thank you in advance
I updated phpMyAdmin to the latest stable version and it worked!
