MeshAnimations import with S3D is an unfinished/imperfect function.
One can edit the file with a hex editor to make it work.
But you need to know exactly what you are doing.

Now. Having said that? Here's what you should do for a best bet import.
DO NOT IMPORT the base 3D model.
Select the 3D model with a starting number of say 000.
You'll get a pop up after that.
Import and keep your fingers crossed.

So if you have edited the base object then created animations?
Import the base object. then save the file.
All the animation frames should be other obj files with the same name but _000 through however frames you have.
Like DC_Man_000.obj to DC_Man_011.obj.
Then open your saved file, do a 3D model import selecting the DC_Man_000.obj
