Theme Installation Failure

Hi,

Tried install a theme, but got this msg:
Theme installed successfully.

Warning: fopen(/home/chrissie/public_html/sheerskinfacts.com/wp-content/themes/WP Template 25214/style.css) [function.fopen]: failed to open stream: No such file or directory in /home/chrissie/public_html/sheerskinfacts.com/wp-includes/functions.php on line 4165

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

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

What do I need to do?

Thanks,
Larry
