borisb, replied to christianbook.com again that necessary items were enabled and got this reply: "We're not sure why you have encountered this problem. We have tested the file and found that there may be a problem with it. We have forwarded all the information to our Technical Department and will contact you as soon as we hear back from them." I will keep the opera browser app in mind if I don't get a solution from them. Thank you so much for your help. I'm sure I'll be back with more questions. (btw, I left a positive review at HSN and watched the latest video. Learned even more about the PE.)
