Who did you order it from? If you got it from stardock then you can download the game. If you got it from stardock, what did the estimated arrival date say? You ordered it on a saturday, so whoever you ordered it from might not process orders over the weekend. Once it's processed, it can take 2-3 Business days to get it shipped. Then depending on the type of shipping and your location, it could take another 3-5 Business days to arrive. Do you have a tracking number? It's only been 5 business days since you ordered, so unless you paid an extra $20 (or more depending on various things) for overnight delivery then chill out!
Why are you posting on the forum instead of emailing someone who can do something about it your order number and nicely asking your question. If you haven't gotten any emails, then check your spam/junk folder, because you may have filtered it out.
