Error after activating plugin

Hi, when I try to activate the plugin I recieve several messages like this:
Notice: wp_register_style was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in /var/www/clients/client4/web47/web/wp-includes/functions.php on line 3792

When I diactivate the plugin the messages are gone.
Can you help me?
