atal error: Cannot redeclare es_load_textdomain() (previously declared in

Hi, I installed Estatik fine a while back but I just noticed it’s de-activated and when I try to Activate it I get this message:

Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare es_load_textdomain() (previously declared in /home/customer/www/websitehere.com/public_html/wp-content/plugins/estatik4-pro-1/estatik.php:38) in /home/customer/www/websitehere.com/public_html/wp-content/plugins/estatik/estatik.php on line 37

I tried uninstalling it and installing (both Estatik and Pro) again and I still get this message. Is there anything I can do?

I have the Pro version, this error occurs when Estatik is activated, then when I try to activate the Pro plugin.

Thanks
