Theme Install Error

Hello
I am in the process of developing a site to make a bit of extra cash
the site http://www.flytripper.co.uk is hosted at 000webhost and wordpress was auto installed via fantastico

I have attempted to install the free theme magasin-uno
http://www.paddsolutions.com/wordpress-theme-magasin-uno/

After install I receive the following error messages:-

Warning: fopen(/home/flytripp/public_html/wp-content/themes/magasin-uno/style.css) [function.fopen]: failed to open stream: No such file or directory in /home/flytripp/public_html/wp-includes/functions.php on line 4165

Warning: fread(): supplied argument is not a valid stream resource in /home/flytripp/public_html/wp-includes/functions.php on line 4168

Warning: fclose(): supplied argument is not a valid stream resource in /home/flytripp/public_html/wp-includes/functions.php on line 4171

When I activate the theme it states that the file is broken and reverts to the default template

Can anybody please explain to me whats wrong.

many thanks in advance
