Yahoo! Messenger error messages?

I am getting these two error messages from Y! Messenger. I would like to know what the problem is. The first is what I get a little more often. It says there is a script error and asks if I would like to continue running scripts. Second one states that there is an 'object expected' (I think it had some object id of 87 or something). It asks if I'd like to debug- If I click yes MSE opens. I'll copy down more of what they say when I get them. My main concern is that I'm missing IMs because of some error that's going on.
