Try Zonker here on Glocals - don't know him personally but he's had good reviews.

I don't know much about Macs but it seems like you're talking about a problem with your internet browser or with the Hotmail website, not with your macbook.

Can you explain the exact problem? Are you trying to access Hotmail in Opera (the internet browser)? Or some e-mail program? Can you log into Hotmail? Can you see your inbox? Does anything happen when you try to open one (e.g. an error message) or nothing at all? Are you able to use other websites?

Easiest way to figure out what is wrong is to try a few different options. Most importantly, try to enter/open/delete hotmail on another computer (if that's easy for you). If that works it's indeed a problem with *your* computer. Next, if you can, get another internet browser (not sure how easy that is on a mac) and check if that works. That way we can make sure it isn't your browser settings.
