I feel honored to be working with you and thank-you for your attention to Sound Forge Pro.
The iZotope Mastering Direct X Suite 2 can be downloaded from the link below. I believe this came with Sound Forge Pro 10. I also recall the iZotope Mastering Suite 1 came with SFP 9, which is the same, but does not have the exciter plug.. (which I do not use much anyway). OTOH, the original Wave Hammer is a favorite.. be it music (i love what it does to drums) and/or dialog.
I have the reg # if you need them. Thanks again for your work.
