Hi @Suhsant,
My advise would be as follows:
Ensure that you are able to download the xls dataset from your user account. If you are able to download the same then you should be able to download the Media Attachment (ZIP) via the Free Download Manager.
While downloading the Media Attachment (ZIP) via the Free Download Manager first download the Media Attachment (ZIP) as shown in the image below.
Then hover the mouse on the downloaded link and right click your mouse. Select Copy link address and paste the same to the Free Download Manager.
You should then be able to download your Media Attachment (ZIP).
Have a great day!
