Branda Plugin Missing


I had installed Branda plugin on the above mentioned website. I tried to update the plugin yesterday but it said ‘Failed: Plugin failed to be installed.’ so I left it.

Today when I login, all the branding is lost and the Branda plugin is nowhere to be seen. So I try installing it again and I get the message:

“Failed: Plugin failed to be installed.

Destination folder already exists.”

Could you please see it as I need Branda to put this site on maintenance mode.
