Fatal Error after Corporate Theme Activation

I uploaded the Corporate Theme and everything seemed to be going fine, and then when I went to activate it I received this:

Fatal error: Cannot redeclare bp_dtheme_ajax_querystring() (previously declared in /nfs/c05/h01/mnt/69317/domains/pdx.readinglocal.com/html/wp-content/plugins/buddypress/bp-themes/bp-default/_inc/ajax.php:20) in /nfs/c05/h01/mnt/69317/domains/pdx.readinglocal.com/html/wp-content/themes/bp-corporate/_inc/ajax.php on line 20

I tried to do a thorough search of the existing topics, and didn't come across anything similar, although it is 1:30 in the morning so I could have missed something.

Any ideas?

Your help is greatly appreciated!
