Tiny MCE - Line 28 Missing?

Have installed and reinstalled the Tiny MCE but when trying to use I get the below warnings:

Warning: include(/home/bookseed/public_html/store/editors/tinymce.php) [function.include]: failed to open stream: No such file or directory in /home/bookseed/public_html/store/admin/includes/tinymce.php on line 28

Warning: include() [function.include]: Failed opening '/home/bookseed/public_html/store/editors/tinymce.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/bookseed/public_html/store/admin/includes/tinymce.php on line 28

I can see the file: tinymce.php is there and it's in the correct directory so don't quite understand. Where is the reference to line 28 coming from?

Any assistance great appreciated.
Many thanks,
Beverley
