I know what you mean. I have had that happen before also. You never know when buying from ebay. I just purchased quilting software and was anxious to get it that I did it as a buy it now. I didn't bother to see if it could be returned. I assumed it would work with Windows 7 (which it doesn't) and now I have a quilt design program that I can not use. Oh well, I will be more careful next time. I will end up trying to sell it on ebay myself.
Blessings!
