Upgrade Problem

Hi,
I just tried updating from 2.5.1 to current version. When I go to
http://mysite.com/wp-admin this is what loads.

Warning: require_once(../wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /bhome/my-user-name-was-here/public_html/wp-admin/admin.php on line 7

Fatal error: require_once() [function.require]: Failed opening required ‘../wp-load.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /bhome/my-user-name-was-here/public_html/wp-admin/admin.php on line 7

What did I mess up and how do I fix it?
Also, When I open the admin.php file with notepad how do I know line seven from line ten? What I’m saying is in note pad depending on the size of the window in notepad (full screen or 60%); you may not be able to simply count from the top down to seven and be assured it is actually line seven.

Any help greatly appreciated.

Thanks,
