If you don't batch import and instead individually import a PDF, does that work? I just want to verify whether this is specific to batch importing in your case, or if there is a bigger problem. Batch importing works fine for me with 4.0.4 with every test I've run, so I need to identify exactly what scenario causes a problem. Is it related to specific files? Are you importing files that already exist in your library? Is the error happening due to a conflict with a new version of a file already in your library? The more information you can provide, the better.

Thanks,
Mike
