htacces preventing me from logging in to my wordpress?

My zencart is installed in my public_html and my wordpress is installed into a subfolder.

I just noticed that this piece of code inserted into my store root htaccess file prevents me from logging into my wordpress admin.

# redirects any URL that includes: /images/wp- with 'wp-' being anything that ends with '.php'
# this allows for images named such as 'wp-header.jpg' to work
RedirectMatch Permanent ^/(.*[images]+)/(wp-.*\.php)$ /page_not_found.php

How important is this code for zen cart? And if it is kinda important is there a work around so it can remain in place and not have it affect logging into my WP admin?

*oh gosh my title spelling is atrocious. I really do know how to spell.

Change the rule to use RewriteRule instead of RedirectMatch.

Add a preceding negative match RewriteCond looking at the requested path.

Set it so that it excludes requests for the zencart folder from activating the rule.
