The YouTube video is just using Animated GIFs - Not sure it's a viable proper workaround, since you still can't use custom gauges showing custom values, you're just showing an animated gif that looks like a gauge, but actually does not function like one, hence why it doesn't show a value, it just repeats it's movement around the number. The number itself WILL be correct, since it's just a normal sensorvalue number.
The Bluescreen error seen comes from my program, I coded that, it's supposed to show if it can't connect to whatever URL you have entered in the settings.
As for Exception Violation, that is a very strange one. As mentioned, you can see from my source code (on github) that my program doesn't actually reference Aida64.exe is any way, shape or form. Since my app is basically just a web browser, built to be used with Aida, it doesn't actually interact with Aida so to speak - you could run my RSLCD Viewer on a computer that isn't running aida64, and just set the url to google.com for example and it would work. So no idea how it's caused that strange Exception error but I'm looking into it
