Here's one of my OBJ files to download:

I was expecting that if Cinema4D can read the OBJ, so would the plugin but apparently not?
I'm sorry but the obj format you are trying to import is not supported by ObjSequenceImporter.
As we wrote on the plugin description objsequenceimporter is dedicated to work with blender.
Wavefront format should be a standard but a lot of 3d software write its "own" wavefront obj format.
Because of this we decided only to adopt the blender export and a few variants.
