How to fix SPECIFIC Internet Explorer Script Error

I’m having an ie script error(s) message pop up on startup. I put ‘specific’ in the title of this question because it’s coming from a network agent I have installed called ‘Cisco NAC Agent’ . The error(s) is stopping Cisco from popping up so that I can login and use the internet.

Here are pics of the error(s) i get. The first happens everytime the error pops up but the second happens randomly but only after the first.

Can somebody please help me out with this? It just started happening after I uninstalled the DANCE!Online program by Acclaim and restarted. I don’t know if that is relevant or not because the two are not related…or are they?
