After Installation /Problem

Hi everybody,
Afetr installation and switch on plugin i see info:

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 88 in /wp-content/plugins/event-calendar-scheduler/codebase/dhtmlxSchedulerConfigurator.php on line 49

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 93 in /wp-content/plugins/event-calendar-scheduler/codebase/dhtmlxSchedulerConfigurator.php on line 147

and some information that plugin back 541 characters. Could some help me ?

Hi,
are this erros shown in admin panel or where?

Please, try to execute the follow query to your database:

SELECT `option_value` FROM wp_options WHERE `option_name`='scheduler_xml';

don’t forget to replace wp_ in table name with your database prefix.
Is result empty or not?
