EZ-Pages Permisions error after editing

Hi

Im trying to edit the standard text on the EZ-Pages and i am getting the following errors and i dont know why.

Warning: fopen(C:/Sites/Single36/name/webroot/omnijet/includes/languages/english/html_includes/theme085/define_main_page.php) [function.fopen]: failed to open stream: Permission denied in C:\Sites\Single36\name\webroot\omnijet\admin\define_pages_editor.php on line 75

Warning: fwrite(): supplied argument is not a valid stream resource in C:\Sites\Single36\name\webroot\omnijet\admin\define_pages_editor.php on line 77

Warning: fclose(): supplied argument is not a valid stream resource in C:\Sites\Single36\name\webroot\omnijet\admin\define_pages_editor.php on line 78

Warning: Cannot modify header information - headers already sent by (output started at C:\Sites\Single36\name\webroot\omnijet\admin\define_pages_editor.php:75) in C:\Sites\Single36\name\webroot\omnijet\admin\includes\functions\general.php on line 21

Thanks

Resolved, due to permissions

Additionally... these are not EZ Pages, but DEFINE pages... (There's a big difference. EZ Pages content is stored in the database, while defined pages content is stored in html.php files.)
