BookSmart by Blurb Troubles!?

So I downloded this program, BookSmart, from Blurb, yesterday, and I forgot what file/folder I put it under. I clsoed it, and today I came back to work on my book again, but I cant find the program! When I search from the start menu, it brings me to the BookSmart link in my favorites. So basically, the search is no use. Also, when I looked under instal/change programs, what do you know, its there! So its still installed-no desk top item, no folder to be seen, I looked everywhere! Please help! I dont know what to do! My entire story is saved on a file I cant find! Please help!
