I have pinnacle studio 17 ultimate running on windows 10 and I have just noticed that my mapped network drives are no longer showing up and I cannot import anything from them. I have it installed on a second machine running windows 7 and there is no problem seeing the network drives. this is quite a pain as the majority of my video files are kept on the network drives. I have a feeling the problem may have started when I upgraded from windows 7 to 10.
