warnings when installing from a zip

Hi - I tried loading two themes today and received the warnings below. Any help is appreciated!

This is the warning I got when uploading the product-theme-1.5zip...

Theme installed successfully.

Warning: fopen(/home/content/j/o/h/john27349720/html/cmglobal/wp-content/themes/wpmu-product-1.5/style.css) [function.fopen]: failed to open stream: No such file or directory in /home/content/j/o/h/john27349720/html/cmglobal/wp-includes/functions.php on line 4165

Warning: fread(): supplied argument is not a valid stream resource in /home/content/j/o/h/john27349720/html/cmglobal/wp-includes/functions.php on line 4168

Warning: fclose(): supplied argument is not a valid stream resource in /home/content/j/o/h/john27349720/html/cmglobal/wp-includes/functions.php on line 4171

This is the message I got at the bottom of the themes page in the admin section of WP...
