parse error after installation

I am new to MODx and installed it for the first time on my server in a subdirectory.
Installation went smoothly, but when I try to access the manager I get the following error:

Parse error: syntax error, unexpected ’.’ in /home/myweb/public_html/modx/manager/index.php on line 122

If I go to Line 122 I find the following:

echo "Please run the MODx <a href="../../../../scripts/modx-0.9.6.1/install">install utility</a>";

This is a path to a directory that does not even exist!

If I remove the link, I get the same parse error for line 138, also with a similar link. There are more lines in the index.php with this type of link.

What have I done wrong.

I am keen to try MODx, but this start is very disappointing and frustrating.

Am I the only one with this problem?
It looks like I better give up and try Drupal instead.

is what’s in my manager/index.php on line 122 etc.
Somehow your install path seems to have gone astray
Is it worth uploading the file again?

Thank you so much. After uploading this file again and /includes/document.parser.class.inc.php because I got an for this file after I did upload index.php again, I got the login page. I will give it a try!
