SF 11 has been working without problem since instillation 3 months ago. Yesterday I endured the 90 plus minute upgrade of Windows 10. Today, SF 11 does not recognize my desktop where I keep music files I've recorded. Pulling down and clicking on "open" does nothing, when it previously would show all file names on the desk top allowing me to import what I wanted. I made no adjustments to SF 11 since it was installed 3 months ago. I see Magix does not provide tech support for SF 11. Ideas what is happening? Places to go for tech support? All input appreciated. Thank you. I've got a DELL xps system, with the tower.
