Hi Dan, yes it's still available from Studica. The link is only gone temporarily because I'm going to be doing a web site overhaul fairly soon and I was thinking of moving it to the purchasing page instead of having it on the main page.

You can get it from here though:

And yes, any version of MoI ordered through Studica is a legitimate copy, thank you for checking!
