E-c-form application

I have uploaded  rem file  for  e-c-form application. After uploading  received  error msg:

Line         Box

2                2   first 4 lines should have one token -improper Rem file

0                 0   Improper Rem file missing tin or version or form date  or tin

The same file I have applied  before filling return ,uploaded without  any error msg. But now when I filled return  & uploaded for c-form  I received  above error msg.

Please reply , if any one  have solution.
