Load Time

Hello: My site was loading slower then normal so I investigated and found that this plugin was the culprit. More specifically the custom date picker java script. I don't think I am using the date picker.

I don't know much about java script but my question is...

Can this part of the plugin be disabled or this portion of the plugin be removed without breaking the other functionality? Here is the string http://hspire.com/wp-content/plugins/custompress/datepicker/js/i18n/jquery.ui.datepicker-.js?ver=1.8.18

All suggestions and options are greatly appreciated.
