Hey man, any luck here? I am not new to recording and have used Ableton and ProTools. I happily switched to studio one 5 and was really digging it. I have my "Save" folder designated to an external HD (Like most other producers), but when I plugged the HD into my other machine today for some remote work, It stated that I had many missing files (and in this instance, it wouldn't even let me locate, or accept them) This seems to be a BIG problem, and like you've experienced, there isn't any help available.
I will reach out to the support team now with a detailed description of what's going on, as this determines how I upgrade my machines, gear, and ultimately my DAW.
