Are you talking about loading your receiver? You probably have the wrong cable. Use BL updater 1.4 and a straight RS232 DB9 F/F cable. - Do NOT use a NULL modem cable.
Follow the exact loading procedure described for the procedure.
I am using the st. cable and BL updater 1.4 loader and it is converted to puff because on Nov.13th my satellite guy sent me puff file and it was downloaded . Even at that time I had tried the same file from this site but I had got the same message and same thing is happening now. My satellite guy is not picking up the phone and he is not responding to email.
