Since the upgrade to my windows app yesterday, I can play about two songs, and then the app crashes and then uninstalls itself. I've never seen anything like it. I don't think it's got anything to do with an antivirus program, as I get no notifcations that it's been flagged or removed. It just crashes and then it's gone from my computer. Gone from the programs list, all shortcuts automatically deleted. The "roaming data" folder does not automatically remove, so I have tried fully removing the app by deleting the C:\Users\[username]\AppData\Roaming\Spotify\ folder, re-downloading and then reinstalling; that does not fix it.
Thanks for your help!
