Hacked Super Flight Planner?

Hi Gents,Need your advice. The Super Flight Planner site still wants me to allow some Turkish crap to come through when I go to the site. I just recently acquired SFP and I would like to use the available tutorials but I'm afraid to turn the pop-up loose. Would you young compter gurus have a look at the site again and let me know if you think letting the pop-up do its thing would be dangerous? I really want to support the fellow who has made this program freely available but I have my concerns about inheriting something damaging in the process. Do you think the creator of the site knows something may not be right? Is there anything we could do to help remedy the situation?Thanks,Grandpa
