Fatal Error with Fundraising plugin

I updated to the latest version of the plugin this morning and got the WSOD.

I uninstalled and reinstalled the Fundraising plugin. When I attempt to activate it I get this error:

Fatal error: Call to undefined function is_subdomain_install() in /mnt/stor12-wc2-dfw1/601094/885276/www.oceanwishes.org/web/content/wp-content/plugins/fundraising/fundraiser.php on line 81

Any way to tell if it's something I did or if there's a bug in the update?

Thanks!
