Well I have tried a few different applications to try and extract the 5-8 ones and still can't get them open. The web said that the ones I used should open in. One said it couldn't figureout what format it was in. I have searched online but still haven't found an answer. Don't know why it was only able to extract the first and last set that you sent me and not the 5-8. I will keep searching.
