Do you have the patch installed? See the appropriate support page for
DKS or
FoV.
You can send the save to support@larian.com, with a description of the problem and maybe a link to this topic.
See Lar's post
here on how to send them an Xbox save.
With the PC version, in XP the saves are in the folder
C:\Documents and Settings\ %username% \Local Settings\Application Data\Divinity 2\Savegames
or in Vista / Win 7
C:\Users\ %username% \AppData\Local\Divinity 2\Savegames
You may need to set Windows Explorer to show hidden files and folders (
XP, Vista,
Win 7).
