This is Rick Perkins. My father is Jim Perkins (jetfireguy). He started this website and I’ve been taking care of it for him for several years now. I’m sad to tell you that he passed away suddenly in January with complications related to his Parkinson’s disease. I found recently that his credit card was used to pay for the site. Since he passed away, his card was cancelled. I believe that is why you were receiving the 404 errors. I’ve updated the site to use my credit card now. Please let me know if you have any more issues.
