Does anyone use Holdem Profiler here?

Well, so I am using the free version and the software allows me to store upto 10,000 hands. How can I delete the previous hands in order to make room for new hand histories? I also read in the FAQ Section that we can even upload more than 10,000 hands but will be able to see only 10,000 hands. Which 10K hands will I be able to access? The newer ones or the old ones?
