I have just attempted to update firmware - followed all instructions precisely and received the following message:
The uploaded firmware file may not be correct. You may have uploaded a file that is not intended for this device, or the uploaded file may be corrupted.
If the uploaded file is correct, it is possible that the device may be too busy to properly receive it right now. In this case, please try the upload again. It is also possible that you are logged in as a 'user' instead of an 'admin' - only administrators can upload new firmware.
The Gateway will not be reprogrammed.
Any advice? I have tried three times, making sure I was logged in as ADMIN, and ensuring that I selected the appropriate BIN file, downloaded to my desk top.
