AE says I'm missing files when I go to collect but...I'm not missing files.

Hello everyone,
I've looked everywhere for help to this issue but to no avail.
I'm working in CS6, not working off of a network nor an external hardrive and my project is finished and rendered and everything is great with the finished product but when I go to collect the source files, AE says I'll be missing a certain file so I go and look for it in the project window. It's there but I relink it just to be sure.

I'll try again. Same thing but with a different file. But always, the file is never missing. I've checked the project window and it says I have no missing files at all. I'll cancel it and try again and it'll say a different file is not found. But as usual, when I check, it's there.

I'm totally at my wit's end with what to do. I've cleared my cache, removed unused footage, anything I can possibly think of but I still get the same problem. And it's not just this one project but multiple projects. Is there anyone here who knows what might be happening?
I'm at a total loss.

Thanks in advance, everyone!!

Thanks for taking the time, Todd. I checked it out and the file names for some of what it's saying is an error aren't abnormally long ( copsmartphone.ai is one name for instance) and there aren't what I'd guess would be an odd character.

Here's a screenshot of what I'm looking at:


You can see on the error it says I'm missing copsmartphone.ai and you can see in the project window there's a file called copsmartphone.ai (the one below the highlight one) with no color bars. So at a loss here.

Any other insight?

Well, you eliminated the file name issue. Now what about the file PATH LENGTH, overly-long file folder names and oddball charcters used to name file folders?

At the moment, based on the information at hand, I can only attirbute it to operating system differences.
