Im having the next problem: I can drag with no problem files from Finder to the After Effects project, but I can't drag files from the project window to the composition or timeline.
If I restart AE and open the project I can only drag 1 item from project to composition window and then I can't no longer do it.
I opened old AE projects and there's no problem, it seems to be a problem with the files in this project, do you think its a software malfunction or maybe some kind of problem with the files, like a virus or whatever. The files are some large PNGs and PSDs.
Did you ever find a solution to this issue? I have a project due in less than two weeks but can't do any work in After Effects.
What are your system specs?
What, exact, version of AE are you trying to use?
