There seems to be a mess of people having problems with V2 of JizzaBeez's save editor. While I haven't tried version 2 myself, I had no issue at the time with the first incarnation; might prove useful to some.
You MUST use XeAlgo after editing to fix the checksum, THEN rehash/resign.
From my own experience, I've had some file corruption issues with containers using USB Xtaf GUI on Win7 X64 that never came up on WinXP X86. (Borderlands saves for instance)
I would recommend using Party Buffalo Drive Explorer for all file transfer operations:

Download - Bayonetta - Save Editor.rar
Download - XeAlgo.rar
I also discovered (and mentioned in the V2 release thread) that you can easily hex edit a save to change which character is active.
Go to offset EF27, and change accordingly:
Finally, if you can't get anything to work, I uploaded a save for this game here:
*Edit* Mmm, looks like someone found an updated version of XeAlgo a few months ago. Give this a whirl if you're having problems loading it: http://www.360haven.com/forums/showt...-XEALGO-FIX-IT!!!
