I don't think it's possible to get a refund. You say that designing a quilt looks too daunting. Is it something you want to do? If you're not motivated to use the software, it doesn't seem to me to be a good purchase. There is a learning curve, and the user interface is not intuitive.
I do use EQ8, having upgraded from 6 to 7 to 8. I consider it one of my most useful tools for quilting. If you do decide to get it, quiltinaday usually has the best price.
