I just upgrade from 1.50 to 1.60 OS for the DPS24 the project that was
loaded (usually I have a blank project loaded during any kind of
upgrade). The Audio tracks vanished showing all them being in an unused
state. The track assignment, mix automation scenes are all in check, I
have never heard of such a thing. there is no diagnostic to see if my
hard drive is going or is not being defrag or align. Nothing in audio
recovery I am just lost for words as to what happen. If this has happen
to anyone please give me some insight so that I don't do it again.
