Actually with software even store credit is something that people really can't complain about.  I can't tell you how many times in the past I bought buggy software and could not get any type of refund.  With some companies once you install it on your computer you're out of luck.  I bought an older product at Daz laz month that didn't work right with the current Poser or Daz Studio and they gave me a store credit  and I used it for something else and I was very happy with that.
