I don't know why but my blog will not load in IE - I'm so glad I just out of boredom decided to check out my blog in IE (I'm a FF user) and when I visited only half of the very first post loaded. I don't know if it's this plugin or my theme, but disabling it removed the error and the site now works in IE 7 & 8 but without wp-cumulus.
The only thing I was able to find in the IE Built in Debugger was:
document.getElementById("StartMenu").style.left = "-1000px";
my blog is http://blog.crazycraven.org
