Issues with Mailchimp Sync and Uptime plugins

I am running WordPress Multisite, and when I have Mailchimp Sync activated, I am unable to delete users from my Network Admin dashboard, and I receive a 500 error. I looked at my error logs via SFTP and found the issue was Mailchimp. However, if I disable the plugin I am able to delete the users fine. Also, I am having issues with Uptime. When I try and enable uptime within Hummingbird, I get a this error: http://screencast.com/t/nnKLGqVXkH7

Please advise...
