With limited knowledge, I really do not know how to do about this win 8 case. My newly installed windows 8 internet security setting keeps prevent one or more files being opened. I think there must be some virus in my pc and have running the anti-virus program but found nothing at the very beginning. After a series testing, I know that there are some security settings that need to be tweaked inside the Internet Options to allow downloads again.
Sorry for so long post. Hope you can help me in this win 8 case.
many thanks in adavnce.
