I had 10+ download but since I login my account today there were all gone???
Please note that envato elements downloaded item(s) will not display in envato market download page. envato market download page will display only your purchased (from envato market) items list.
This is not the cause.
The page used to show all my downloads but today when I log in, they were all vanished.
If you mean envato elements download then you should check here envato elements by loggedin there.
Otherwise please open Help ticket and let them know. Envato Customer support team will be happy to assist you.
