I am uploading EX4 File it says Inavlid Signature ? Can anyone resolve this

 
I am facing issue when i upload my EA ex4 file it says invalid Signature 
 

“Invalid Signature” means that one of the following issues exists:

  • The EX4 file is corrupted or incomplete
  • The file was compiled with an old or invalid version
  • The file was not downloaded from the Market but is protected
  • Or it is not compatible with your current MetaTrader version

uploading from where? to where? This is a technical forum, so if you want any help, you need to provide much more information. Or this thread will continue to be ignored by others.
