Accidentally deleted something and now site doesn't work

First off, I am not very savvy when it comes to this stuff.

Okay, I got distracted by my kid and somehow deleted the configure.psp file when I was in filezilla. I didn't think it was that big of a deal. I went back onto my computer and uploaded it back. I double checked to make sure (by date) that I didn't alter anything else

Now if you go to my site: https://www.thebeveragegourmet.com, you get this:
Warning: main(DIR_WS_TEMPLATEStemplate_default/common/html_header.php) [function.main]: failed to open stream: No such file or directory in /usr/home/kwe/domains/thebeveragegourmet.com/public_html/catalog/index.php on line 43

**I have NO IDEA what that all means. Can anyone help?

check to make sure you uploaded the right one. there are 2 configure files that are different. one resides in admin/includes/configure.php, while the other one resides in includes/configure.php

*I don't have a configure.php in the includes file. I only have one in the admin/includes file...

I see the file on my webserver but not in my original downloaded files on my computer. Is there a way to download that file and then upload it to it's place? I had no idea a slight slip of the mouse would do so much damage

If you do not have a copy of your /includes/configure.php you could make one from scratch by copying the /includes/dist-configure.php to /includes/configure.php

Then look at the /admin/includes/configure.php on your server to see how to fill in the custom defines for your site ...
