When I moved to Mint I did a back up of my files and now am confused, because all the files are the same type, wma. and have the same properties audio (audio/xmswma) yet some I can play and with others I can not because of this Encrypted and decryption not supported ! I can't work out why that should be as all were in the same file on the windows 10 thing. I have looked on the forum for help but I couldn't find any. If there is then sorry, please direct me to it. If not then is there a way to resolve this please? I have already search online, but too many different answers and I know I can trust people here. Wine doesn't work or perhaps I don't know where to look on there. Thanks for anyone who answers - just remember I've only been using mint for a week so please be patient with me.
