Brandon, there is obviously some reluctance to being the one who tells you all may be possibly lost.

However, you say that restore failed, is this because you found a backup and clicked on redo and that did not fix it or were there no backups available?

If backups exist it is possible that renaming some files in the project directory may fix the issue, so assuming there are files in the backup directory in the project folder please supply a screen capture of the actual project directory so we can advise.

Can we also assume that you have never gone to step 5 and exported the project in order to create an iwzip file (the only true backup including source)? I note that this type of error has beset you before, in future please regularly create the iwzip (& rename if you want multiple fall back positions). Whilst error in xml document still happens, it was much more common in older versions.

Please advise
