Yes, this could turn out that things are possibly conflicting somehow, maybe changes.dat labeled persistence and a file named persistence, I don't know but the best thing you can do in my opinion is to start really from scratch, blanco.root@debian:~# ls /lib/live/mount/persistence/sda2
026-kernel-3.14-Pae.tar.gz libx32
026-kernel-3.14.0.bpo-pae.squashfs live
Readme-initrd-3.14-pae.txt media
bin menu.lst
boot mnt
cdrom opt
changes.dat pburn_symlink_tree
changes_old.dat persistence
dev proc
etc root
grldr run
home sbin
initrd61.img srv
initrd62.img sys
initrd63.xz tmp
install_flash_player_11_linux.i386.tar.gz usr
lib var
lib32 vmlinuz1
lib64 vmlinuz6
This does not look good to me and needs more information.
You have in root of sda2:
Try moving the files from sda2 to somewhere else (most important move changes.dat, persistence)
----------------
Edit: But don't move them to the root of another drive/partition, just inside a folder otherwise it could still be found when in menu.lst changes=/changes.dat
Btw, no other changes.dat or persistence present on another partition? Could conflict also.
----------------
And create new savefile instead.
As before, I keep believing in a simple cause of the problem.
Good luck!
