Fatal Error

I’ve been using this plugin to post two different slides on my homepage and ever since the newest WordPress update, it won’t let me post two different slides anymore. The error:

Cannot redeclare post_slides_slides_default() (previously declared in /home/content/p3pnexwpnas10_data01/76/2543476/html/wp-content/plugins/post-slides/skins/default.php:3) in /home/content/p3pnexwpnas10_data01/76/2543476/html/wp-content/plugins/post-slides/skins/default.php on line 3

/home/content/p3pnexwpnas10_data01/76/2543476/html/wp-content/plugins/post-slides/skins/default.php:3

I tried finding another plugin similar to this one with no luck. Any help would be appreciated.
