Media Pending Forever, Export Problems, Etc Etc Etc

Everything was working fine a couple months ago.

However, all my media was scattered around in different drives/folders. I consolidated them all into one drive/folder, and relinked everything within Premiere. It seemed to be successful.

Now I am trying to do another export of the timeline in higher-quality and it just gets stuck forever. I noticed that all my clips are displaying "Media Pending" and even if I let it sit for a full day, nothing changes.

I tried several solutions I found online including:

- Close large timelines and bins, save, close and reopen Premiere (no effect)

- Un-enable and re-enable all clips in timeline (no effect)

- Delete and reload Premiere's preferences (no effect)

- Make small tweaks to a clip, such as adding a cut or removing/adding a frame (no effect)

- Create a new sequence and copy-paste everything from the old one into the new one (no effect)

- Started a new project and attempted to import the sequence from the old one (displayed no sequences from old project)

None of this has worked.

The timeline claims the media is "offline", which begs two questions:

a) Why doesn't it just say "Media Offline" instead of "Media Pending"?

b) What was the point of spending all that time relinking my media after I moved my files?

The one thing that HAS worked is restarting my computer; I was able to successfully get my timeline to display all my media—HOWEVER when I went to export the timeline, it hung up at 1% telling me there were only 6 minutes remaining (which I know could not be true, since several months ago when I exported a version half the size/quality it took 2 hours).

As always, queueing it Adobe Media Encoder fails (this seems to happen about 95% of the time I use AME)

I need to get this exported within the next couple days and since it needs to be maximum quality, I know the render is already going to eat up a lot of that time so I need to find a solution quickly...

Any suggestions are appreciated! Thanks.
