I use BP on two other sites without problem. Running WP 3.4.2 and just tried to install BP 47.6 twice. After the install, the only thing showing in the control area is the warning about the .htaccess file, the link to rate the software and the link to upgrade to Pro.
Ideas? I've uninstalled and reinstalled the plug-in a couple of times, making sure both times that the plug files have been deleted with an FTP tool.
Below (hopefully) is an image of what I see:
