I recently purchased the MCSE Exam 70-230 Microsoft Biztalk Server 2000 book from a discount book dealer over the internet. It came with only 3 of the 4 CDs, 2 sealed, one not. The missing CD is the Supplemental Course Materials. This is the most important one for me, as I did not need the trial versions of SQL Server, Visio and Biztalk that came with the book. Does anyone have this CD or know where I can get it without repurchasing the whole book again? Would you be willing to share it (I can provide proof that I purchased the book) or sell it to me? If so, please contact me at senior dot programmer at gmail dot com, or respond to this posting. Any help would be much appreciated. Mark
