Did someone invoke a Stardock employee? 
We've tested this recently so I know it works. Add demigod to your cart, choose the option to buy for someone else, enter in their email as much other data as you have, enter in yoru paymetnh options and you should be fine.
If something fails, shoot me a PM and I'll look into it.
Sales and support do not work on the weekend . . so do it today or wait until Monday in case somethign *does* go wrong.
