Query: Webpage doesn't work, no datasets

I got this book thinking that since I use S-plus as a derivatives trader at a Bulge Bracket I-bank, how great it is that a Princeton Professor would use this statistical software package to do all sort of analysis of Financial Time Series.Sorry to say that all the datasets that he refers to in the book and that are necessary to do the problem sets are not available. The webpage he constantly refers to in the book just does not work, and none of the other links on his homepage refer you to the datasets.Don't buy this unless you want to waste your money.
