Back in March, I downloaded and installed Untangle for the first time and just got around to configuring it today. When I got ready to download some applications, I was told that I had to upgrade. I completed the upgrade and it rebooted. After getting through the boot up screen with the Untangle logo and the load bar, the next screen is a bunch of flashing bars on the display that goes nowhere. I burned a fresh download of 6.1 and installed again with the same issue. It is completely non-functional. Any ideas? I am using a new Dell desktop that meets all the requirements.
