After some bureaucracy, I finally have access to software. I still don't know why it took MS longer to allow me to use my subscription than it did for NewEgg to ship me the physical media, but some mysteries aren't worth knowing.
The next odd thing was getting Microsoft's file transfer client installed. It took a few minutes work to find a download site, download and install the client and then allow IE to use the client.
Now, I need to download and configure Windows XP, VB 6 and Office 2003, all in a VHD. I've got all of the required ISOs, so I'll be installing up a storm on the train.
