Hey guys,
I have just installed the SD-Card adapter in the box according to the how-to´s. I have done a check afterwards and all tonies were working fine with the original card, what means that the attaching was done correct.
I have then inserted a new SD-Card (formatted to FAT32) with a content of copy of the original card. I have put an original tony on it to see if it works, but the box started to blink red, so the new SD seems not to be working.
So I have added the original card again. Unfortunately I have the same issue here too now 
Box is blinking red, Tony is not playing anymore (Original Tony - Original card).
Do you have an idea what I have done wrong ? Have i destroyed the box 
?
Best regards,
Hazling.
EDIT: After restarting the box both cards work. Lessons learned: When changing the card, restart the box 
Sorry for the post
