I'm getting an error:

L 01/02/2016 - 05:24:43: [SM] Unable to load plugin "tAutoDemoUpload.smx": Native "EasyFTP_UploadFile" was not found

This is the native:
native EasyFTP_UploadFile(const String:sTarget[], const String:sLocalFile[], const String:sRemoteFile[], EasyFTP_FileUploaded:func, any:data = 0);

Any help on fixing the Native?
