Can't import video twice

[Andrea5CB1]

Hello. I have a very serious problem. From this morning, I can't import video. I import one video, it appear on the timeline, then I can't import others videos. What can I do? I try all import mode.

Most common user error is not source patching the track.
Solved by first opening clip in Source Monitor, set in and out point. Then drag/insert into timeline.

I've tried this with no results. My premiere import one file, then, it doens't import anymore. This is happening with all my files, also files that I have successfully edited in the past few weeks.

i really don't understand what's is going on. Now, I can't import multiple files: Premiere import only on file, and after this, I can't import nothing in timeline. I've updated Premiere with no results.

I've try to open old projects: they don't work anymore (I can't import in timeline)

That is what I said: source patching.
