Problem with FTP_Client

Hi,
Did you use ftp client from keil? I have lot of problem with this stuff. It sometimes call handler ftpc_notify multiply after operation on file:

if (ftpc_connect (srvip, 0, FTPC_CMD_GET, ftpc_notify) == 0) {
    printf("Connect failed, FTP Client not ready.\n");
  }
  else {
    printf("FTP Client started.\n");
  }
}

It return

//[ERROR]-NotFound
//[OK]-File operation
//[ERROR]-FTP Server timeout

when file is not found on server.
Sometimes it reurn:

//[ERROR]-NotFound
//[ERROR]-During File Operation
//[ERROR]-FTP Server timeout

Sometimes it call that it is not ready for transaction.
Did you test it? I contacted with support but I think they do not care about their customer
