Hi Frank,
I deleted my sd card and I've done installation from the beginning. Now the music normally plays, I have no idea why it didn't work the first time.
But my library window is still empty. It's not empty every time, but I would say if I click on the library 5 times, 4 times it is empty, and only one time I can open it normally. I attached picture of my library so you can see how it looks.
I tried with different runeaudio web adress, the one you gave me yesterday and the same thing happens.
I did some testing of it;
I'm accessing rune with my laptop through mozilla firefox, I tried to turn off adblocker and the library is still blank.
I tried with internet explorer, library still blank.
Then I tried with tablet, with 2 web browsers, still blank.
I tried with rune app for android still blank.
Once more I must point out that it's not happenning every time, but like 80% of times.
