Having issues with jQuery Validate Plugin and IE8

Having issues with jQuery Validate Plugin and IE8

I was trying to use the simple date validate and saw it work fine on the demo on chrome but when I tried it on my project, I kept getting: 'settings' is null or not an object

I went back to the demo site in IE8 and it's not working there either. I've tried a few other random web sites that had blog postings about the Validate plugin and I tried their samples in IE and they don't work there either. Most have javascript errors, where there are no errors in Chrome.

Is there a known issue with it?
