atcontant fatal error

Dear Sir,
i am using atcontent from last some weeks, it was working fine but before 2 days it was disappeared from dashboard automatically, when i checked my root directory plugin was there but that was not showing on the dashboard, now i have removed the previous atcontent and upload a fresh copy of plugin now it is giving me this error.

Plugin could not be activated because it triggered a fatal error.

PHP Error Message

Warning: require_once(include/atcontent_service.php) [function.require-once]: failed to open stream: No such file or directory in /home/a4896732/public_html/wp-content/plugins/atcontent/atcontent.php on line 15

Please guide me how to resolve this issue.
