Something Wrong with my mu / buddypress install??? wpmudev themes install with error and won't

Warning: fopen(/home/xind/public_html/wp-content/themes/bp-corporate_1.1.7/style.css) [function.fopen]: failed to open stream: No such file or directory in /home/xind/public_html/wp-includes/functions.php on line 3697

Warning: fread() expects parameter 1 to be resource, boolean given in /home/xind/public_html/wp-includes/functions.php on line 3700

Warning: fclose() expects parameter 1 to be resource, boolean given in /home/xind/public_html/wp-includes/functions.php on line 3703

That's the error I'm getting when trying to install the theme via the theme installer in wp-admin.

Also, even though registration is turned on, visitors cannot register, is seems to have a redirect loop? I can only add new users and blogs manually...
If anyone can help me fix my site, it would be most appreciated.
