If they had some awesome customer service here on Impulse, they might give me a free gift card for $5 or $10 bucks just so I don't feel like such a chump for having spent $40.
Did you check with customer service or hope the CS happy folks would be prowling the forums looking to pass out refunds? 
I emailed Stardock and they made things right. Drop them an email...you may be surprised.
Yup - it's always best to shoot an email off and see if you find a sympathetic ear. Beats venting about it on a message board anyway and tends to be much more effective. Sales@stardock.com - just explain what happened and ask if they are willing to refund the difference. They certainly don't have to, but I've found Stardock to be quite reasonable in the past. Anyway, worst case you are out the 2 minutes it took to craft and send the email. Best case, you just saved $20.
