Not able to view my categories

I am getting this error message:

Warning: require(includes/modules/category_product_listing.php) [function.require]: failed to open stream: No such file or directory in/home/username/public_html/store/admin/categories.php on line 639

Warning: require(includes/modules/category_product_listing.php) [function.require]: failed to open stream: No such file or directory in /home/username/public_html/store/admin/categories.php on line 639

Fatal error: require() [function.require]: Failed opening required 'includes/modules/category_product_listing.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/username/public_html/store/admin/categories.php on line 639

on that line it says this:

require(DIR_WS_MODULES . 'category_product_listing.php');

What is wrong?

(I did just install a newsletter subscriber module. I think the file may have over written some coding, but not sure).

Can anybody help me with this? Not sure what I need to do. Help please!

Looks like I am missing the Category_product_listing file but i can't find it and I am not sure I ever had one to begin with. I just installed a module but that file was not included in the files for it. Not sure what to do. I can't view my categories in admin so I am not able to do anything with my products. Can someone please help me?

That file should be in admin/includes/modules and should be about 30Kb in size. If it isn't there, re-upload it from the Zencart zip file.

Thank you. They didn't include the admin folder name in that path so that helped a ton. I thought I looked everywhere. Feel stupid now, but that fixed it. Thank you!
