I thought I would bring my issue up here as well.
I've sent an e-mail in to Sales@stardock.com as well.
I bought a retail version of Sins a good while ago, installed it, played it and tossed the box. Well, I found out too late that means I can't get my updates. I've lived with that as i'm not going to pay another $30.00 to buy a second copy of the game.
However, I just bought the digital download of the expansion from impulse and come to find out, they won't even let me downloaded it unless the original game is registered with them.
As I'm not buying the game a second time, the only options I see are that the Sales guys help me download it somehow since I bought it, or refund me the money and I'll just go buy a local copy.
As it is, there is no warning whatsoever that buying the expansion is dependant on registering your first one. I'd be happy to register it, I'm just unable. i could take a picture of my CD and book I reckon, and I could probably dig back through all my credit card statements to find the purchase I did at best buy for it, but that's about all I can do to prove I own the thing.
Honestly though, owning the original is out of scope for my complaint. My complaint is that I bought the expansion but am being denied the product that I bought.
Thanks.
