k800i XS ++ GDFS Backup Problem

Ok, my k800i is cid53 so i need to use xs++ 4.1
I installed it into my ubuntu installation and it runs like normal, but when i click "Read GDFS" after connecting my phone i get the following. I am running XS++4.1 as root and have made sure it has write permissions (if i right click and go permissions, everything is set to "read and write" not just the default "read").

Code:

[-------------GDFS Backup Routine-------------] Created '/Backup' dir! Sending data/loader/db2020_cid0blue_recovery_p3n.bin...

Checking if loader is unlocked... This loader is UNLOCKED Backing up the GDFS... Stated variables: 1382 Backup: Error (Could'nt create the output file!) [-------------End GDFS Backup Routine-------------]

What is this error? I've tried google but it brought up nothing. How can i fix it or what's an alternative to back up my GDFS?

I've read that KulanKendi can backup GDFS for free so i downloaded it to my windows OS but i cant see a "go" button, only a tick box for "Read GDFS". Can anyone shed any light for me?

Any help will be greatly appreciated!
