I'm using M8 2.02 and this problem just began yesterday.
Even after "saving" project, when I reopen M8 and reload the project, the most recent media I imported, does not reset itself into the Layers. The layers just read "loading." In this case, they are loading identical media with different settings. (trippy effect!)
Individuals settings within each Layer ARE still there, just no media and each time, I must begin anew. It is not possible to bring in the same, or any other media into a layer where it is "loading."
"Use Document Configuration" is selected in Preferences as I read here elsewhere. Even after switching from Default, the problem still re-occurs.
I am running 10.4.4
This is most frustrating asyou can imagine. Much Thanks & plur, Phoenix
