Volumio is stuck on playback screen

Dear Volumio Help Forum

I have a Raspberry Pi 2 Model B and I cannot get it to work with Volumio. I tried flashing the Volumio image file onto an SD card (done it twice), but unfortunately I cannot use the web UI. Every time I join, it gives me an hourglass and there’s a small green line going from one end of the screen to the other, but never reaches it. I tried all the online forum helps I could, but no luck.
Can you help me with this, please?
