you've hit the nail on the head mate.
It's your driver settings,you just need to change them.
but first i need you to check something,coz when you install MAGIX it also installs it's own AOSIO drivers & VST-DX Adapter Light.
but because you've up graded/dated windows these mite have changed,moved or even gone.
so open magix music editor 2.0 from the program files / magix then open a new project,click on the red OPT record button then choose your settings.
what are your options in the RECORD DEVICE AND FILE PATH drop down? let me known @
