Enable Error Reporting
Although it may be turned off on commercial hosts and production sites (for good reason, so that users do not see the errors), these errors are one of your best tools for troubleshooting. To enable error reporting, temporarily edit your index.php file (normally located in your root directory) directly after the first opening PHP tag (do not edit the actual file info!) to add the following:
<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

Fortunately I found the solution here http://thread.gmane.org/gmane.linux.drivers.ndiswrapper.general/3121 , which is to add these lines to /etc/sysctl.conf, and run "sysctl -p" to update the settings:
kernel.shmmax = 67108864
kernel.shmall = 67108864
