Hi Lionel

Since nothing else changed, it looks like your old downloads.dat and downloads.bak files have become corrupted. Without those indexes stored in the bak and dat files, incompletes cannot be successfully resumed or completed.

This has happened to me before after a java memory crash.

Nothing has been developed (though there has been some discussion of a theoretical way to reconstruct an incomplete file) that will fix this, so the only sad workaround is to delete the whole incomplete folder, and a new one will be re-created with fresh downloads.dat and .bak files on startup.

Maybe in the future someone will find a practical way to revitalize incomplete files withouut a .dat and .bak file, so maybe archive the old incomplete folder just inn case.
