You should disable djmount.ini (rename it to djmount.init.dis) and remove the:
/mtd_content/database/Ace.dat (and Ace.log)
reboot TV, now i think you can enter the curlftp folder and navigate subdirectories as deep as you need.

When i started this i got this:

insmod: can't insert '/mnt/lib/modules/3.8.13/kernel/fs/fuse/fuse.ko': File exists
fuse: mount failed: Invalid argument

can somebody help me to mount ftp in a virtual usb? Smb is working good.
