I'm running Windows Vista and Internet Explorer 8.0. I'm trying to access the following website (http://coursenet.tuiu.edu/), but can't get the window to open. It just keeps trying, but doesn't open. I'm currently on a business trip and using my computer from a different location. I've been accessing this website for the past 8 months, but now I can't. I've contacted TUI Technical Support, but they couldn't find anything wrong. I've also contacted the hotel's ISP provider (Sprint), but they claim there are not any websites blocked at this hotel. I can login to the website from the library, so I know the website is operational. I've tried accessing the window from a DSL broadband connection and via wireless internet. My security settings are set at Med to High. If anyone has any suggestions, sure would appreciate the help.
