Getting errors when opening my files with Adobe after upgrading my plan to Business

Hello Nancy,

My ticket number is: #23584251.

I just figured out that my team-members experience the same problems.
Also when I am on my laptop, I have problems opening files.

My syncing status is:

 (this is Dutch for that everything is good)

When I open an AE file, I get this message:

The document this window refers to is a valid Photoshop document. Nothing is wrong with it. Before my switch to Dropbox Business nothing was wrong with it.

Then I get this message:

The files are there. In the same folder they are always. Nothing is missing.

Then I get this message:

"Error reading past or end of file." I have no idea what it means, but I can say one thing. Before it did not occure. 

Then I get this error. (this is all before I even click once in my project!) 

Why does it want to reopen a opened file? It was not there before.

Now I am finally in my file, it says that there are two files missing.

If I then relink the footage, I get this errors:

WHat is a 'GJEP' file? No idea! Nothing is damaged, nothing is unsupported.

I have no idea what it means, but I cannot relink a file that is on my Dropbox.

Last final error:

I work on two computers (a Mac Studio and a Macbook pro). I seem to have fixed it on my Mac Studio, but if I open that file op my laptop, I get the same errors. Also my team members have the same problems. 

So it looks like it cannot detect the paths of some linked files, and it gives a lot of errors.

I have no idea what to do now. And this is only After Effects. Illustrator and Indesign also give problems, although the re-linking of the files works there. 

Please help me find a sollution,
