.htaccess Problem Loading A Sub-Directory

I have WordPress 2.2.1 loaded in my root directory. I have a subdirectory to a “OS Commerce” catalog script running in it. My problem is that I can’t get access to the control panel of the catalog admin. Everytime I try, I get an “error 404” within the WordPress screen. What is puzzling me is that up until a few days ago everything was working fine. The catalog itself is still working fine.

I came to the conclusion that the problem is in one or both of the .htaccess files. Therefore, I have spent the last couple of days trying figure what the problem is there. I have been trying every variation I could find, both on the WordPress forum and other places, to find a solution to my probrem. Hopefully someone can help me. Following is the 2 htaccess files:

******** Root .htaccess ********

php_flag register_globals on

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

******** Catalog Admin .htaccess ********

# This is used with Apache WebServers

# For this to work, you must include the parameter ‘Options’ to
# the AllowOverride configuration
#
# Example:
#
# <Directory “/usr/local/apache/htdocs”>
# AllowOverride Options
# </Directory>
#
# ‘All’ with also work. (This configuration is in the
# apache/conf/httpd.conf file)
