I have got the zip of Prosper202 I want to install from the official website and it downloads fine without a problem but when I am trying to unzip the zip file I get the following error:

“End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of prosper202.zip or prosper202.zip.zip, and cannot find prosper202.zip.ZIP, period.”

The two last commands I run are:

sudo wget http://prosper.tracking202.com/apps/download/latest/prosper202.zip

and

sudo unzip prosper202.zip

I would appreciate any help, Many thanks!!
