A thought - I know this is super simple stuff, but are you trying to access over and over with the same connection? If so, suggest you shut down completely for about 20 seconds, reboot, bring up your browser, and try again. Last night I couldn't get a receipt to upload to Maritz - it would load 76% and stop. I couldn't find any windows open to cause a problem. Finally gave up, shut down, came back up, and WOOHOO there it goes. Must have had some little dodah hanging somewhere. If you haven't tried that, you might want to take a shot at it.
You have now received friendly technical advice from a computer illerate.
