Fatal error after adding IP address to

So far, I am loving Limit Login ! It has helped me with some issues I was having with my site, but right now I can’t seem to even login. After adding a IP address to the blacklist, I tried to login again and it shows the following error. Where the XXXX is, is my login information. Has anyone ever seen this error, and what are the steps to fix it ? Thanks for the help !
