Error on Mailchimp Sync after updating


After updating my Mailchimp Sync plugin, my wp login screen doesn't come up, and there is an error on a white screen. Also, after bypassing the login screen to get to my dashboard, there are errors in the Mailchimp Sync settings section, as well.

Error in login section:

Fatal error: Call to a member function register_scripts() on a non-object in /nfs/c03/h02/mnt/52377/domains/ on line 42

Errors in MCS Settings section:

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /nfs/c03/h02/mnt/52377/domains/ on line 256

Please let me know if you need any more info.
