I've never encountered that particular error before...sorry I can't help you, but someone around here ought to be able to.
Though perhaps there is a problem with your TDM mod installer... Maybe the file has become corrupted somehow, enough to give you the error you're seeing. If you have a fast enough connection, I'd suggest re-downloading, just to be sure you have a pristine copy of the files.
