wordpress-https.3.3.6 broke my wordpress

installed wordpress-https.3.3.6 and I was no longer able to get into my wordpress admin. I managed to back out the plugins in mysql admin so I can get in now but this is a problem. Is anyone else seeing this? How do I enable this plugin and have things work?

When I couldn’t get into my wordpress admin it would take my username/pw and just keep giving me back the prompt. During that time someone bought something on my website and I didn’t get any notification. Further I tried to use the “forgot password” link and I only got the emails after I managed to back out the plugin.

Thanks
