I am also getting this type of an error, but only on certain jobs. When I am backing up our document management folders, which have filenames with special characters in them, such as 6%#_01!.tif, the xml log generator cna't interpret these filenames, and generates a filename that is not correct. Then, the log is incorrect and corrupted.
Is there any way to change the log structure that is generated, and have it as straight text initially, as it was in previous versions?
