Site broke after initializing Upfront / Spirit Theme

After activating the Spirit Theme I tried to launch Upfront and the system froze ... when I tried to log back in the site was not accessible any longer .. the attempt to login times out and an error message is displayed. The site URL is http://craftycase.ca/wpblog This also happened yesterday and I deleted the entire WP installation, as I thought I had done something wrong ... seems there is an incompatibility with WP and the Spririt Theme or Upfront editor??? Please advise as soon as possible. Thanks.
