Menu Not going to Articles

From the top menu, the menu does not go to the articles. It takes me to a page with the following text.

Who we are



Warning: require_once(/home7/landsce7/public_html/components/com_mailto/helpers/mailto.php) [function.require-once]: failed to open stream: No such file or directory in /home7/landsce7/public_html/components/com_content/helpers/icon.php on line 43

Fatal error: require_once() [function.require]: Failed opening required '/home7/landsce7/public_html/components/com_mailto/helpers/mailto.php' (include_path='.:/usr/lib64/php:/usr/lib/php') in /home7/landsce7/public_html/components/com_content/helpers/icon.php on line 43

What does this mean? Why won't the menu link properly?

Make sure that file

/home7/landsce7/public_html/components/com_mailto/helpers/mailto.php

exists on your server (use FTP software to check this).

It was not. I downloaded joomla and ftp the folder in. I used hot start to launch the site. You may wanna check the hotstart file for missing joomla info. Thanks a lot. Have a great one.
