Blender Inports nothing

I’m trying to import Designer objects from Cryengine EaaS but none of its export formats work, they all import into 3DS Max without a problem.
In Blender you click on import- it goes back to the the blank Blender window, no sign of the object…
I even tried exporting from 3DS Max, same thing, importing files seems to do nothing.

Is it bugged? its not the files as they work fine anywhere but Blender.

Supply an example file

What file format are you trying to import ?
What import settings are you using ?
Is the object showing up in the outliner
Is the imported object very very small
Is the imported object very very big
