DirectiXer

Hi.

I had purchased Directixer version 2.5 a long time ago for same price 49. However the old email address on which I made the purchase is lost. I have a copy of the invoice but there is only the product ID, no serial number. Where can I enquire to obtain back the serial number ? I am setting up a Win 2000 virtual machine with old software because I need to load old vst's back in Sonar 2.
