x2egg converter

The x2egg converter is not working properly. I have got .x files converted from .3ds files. When I used the x2egg converter in command line I am getting error like:
cannot read binary .x file at this time
can not open box.x file
can not read box.x file

I tried with the .x file in the panda directory as well as myfolder directory. But I get the same error.
can some one please tell me how to use this.

AFAIK the x2egg converter does not support binary .x files.
