Windows clients not able to FTP after security update 2009-0006

Question

My FTP server hasn't changes in over a year. Recently, a client complained that they were seeing strange things when they logged into the FTP server.
What they used to see was a series of folders that stated 'Permission denied' and one single folder that had their name on it that they had permission to access. How I accomplished this was to set up an FTP folder and through ACL give them read/write permissions, but deny full control to all other clients. This way they can't see anything but their own FTP folders.
After the security update, what my clients now see is a list of files with names like this:
drwxr-xr-x 4 administrator staff 136 Dec 15 15:35 [client name]
Total 80
Warning: [client name]: Permission Denied
Warning: [client name]: Permission Denied
Warning: [client name]: Permission Denied
I think this issue started after I installed the security update 2009-006, but I can't be sure. What's strange is that I can login using a clients username and password using Transmit on my Mac, but when I try gain access using Windows XP and connecting through network places, I can't get in.
I did read in another posting about reverting to a backup of the ftpaccess file in /Library/FTPServer/Configuration folder. I compared my backup to the live server and they are the same...
Any help would be awesome, as I'm not exactly a trained IT guru...
