First, I extracted DRAKS0005 from my DS profile transferred from xbox360 to my Sandisk, using USBXTAFGUI.exe
I used "Dark Souls Beta 1.2.0.0" to edit my DRAKS0005
I only modified the 3rd slot
Then used USBXTAFGUI.exe to insert the modified DRAKS0005 back to Sandisk
But when I cut the DS profile from Sandisk to xbox360, the game says Save corrupted

Now I have only the edited profile.
Is there any way to repair my DS profile ?
I have played this game for more than 1000 hours
I just don't want to lose my characters that I spent so much time on molding.

Badly need your help!!!
