The Geek Man on "Fatal Error in FeedWordPress crashed my site"

Can someone please help me resolve this error?

My site went down this morning after months of using FeedWordPress successfully (except for duplicate posts).

These were the error messages (my domain name removed for privacy):

[21-Mar-2014 14:52:07 UTC] PHP Warning:  require_once(/home/mydomain/public_html/wp-content/plugins/feedwordpress/externals/myphp/myphp.class.php):
failed to open stream: No such file or directory in /home/mydomain/public_html/wp-content/plugins/feedwordpress/feedwordpress.php
on line 105

Thanks for any help you can provide.
