% in FTP directory name

I cannot change to a directory on an ftp site with a "%" symbol in the directory name, such as "090304_100%CD_Set_Final". Is there any way to be able to connect to this directory using DOpus? I can access this directory using other ftp programs.

Here is a portion of the log:
