Urgent - Credits Still shown on activetedpaid theme

Hi
I've buy the BonAppetit theme on your site and I've actived it, and the credits are dissapeared.
Well, then I've modified the library.php file included in the theme (a simple change on a "Read more" tag) and guess what? the credits re-appeared in the footer. I've also upload a backupped version of this file but nothig changed.
you can see it http://www.lafattoriadipavia.it/2015/
I'm so dissapointed...
Hope you help me to fix this quickly.
