PDF won't open unless I reboot.
I have recently updated Acrobat reader DC as well as adobe flash. When I turn my computer on, reader works fine. But after using a couple different programs PDF files will no longer open and I get a message that says: "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item". If I restart the computer, all is well again...for a while. I am running windows 10
