I finally managed to get it to work. I compared my DNA to each of my grandparent and the results are, I'll admit, completely Greek to me. I'm not sure what exactly I should be looking for? The number of times we match, or the Mb's, or the number of single strands vs. double strands? For what it's worth, here are the results if anyone is willing to explain them to me in layman's terms. :)
