Hard to say without the file.
 Maybe it is not compatible with LibreCAD. Too new version? LibreCAD supports up to dxf 2007.
 3-D file? Does it open in other CADs apart from vectorworks? Does Tool - Select - Select All show anything? Layers off? Does it contain images?
If you like to share the file here you can zip it to make it smaller.

Edit: maybe a binary file? ASCII less troublesome.
