I was just wondering if you found out, whether you had posted it already?
That happens to me all the time! The instructions below will work on other websites too. I've more than once purchased the same design before I started searching to check to see if I had that design, or just in a diffferent size.
The problem I run into with that is some websites just list the number of the purchase and you have to seach through each purchase to see if you have a duplicate. Further, some sites will tell you that you don't have that design, but won't tell you if you purchased a different size of the same design.
I use Internet Explorer and it has a search engine. It's sort of a shot gun approach. If I'm looking for a file that has the word "skeleton" in it, it'll bring up everything in your computer that that that word in it, not only the embroidery ones. So, I often put the format that I use in there too, like "skeleton+pes." That narrows the search.
