[Plugin: s2Member® ( Membership w/ PayPal® )] 10/3/11 upgrade breaks entire website

I upgraded to the new S2Member update this morning and immediately lost all access to my website, including the dashboard on the back end. I was able to delete the updated files and reinstall the previous version through my webhost, and my site is up and running again. I see I am not the only one with this problem. I recommend you remove this new update from the system immediately.
