Addons won't download

Curse client worked fine before WOW 2.4 patch, now nothing will download at all. You click on download via Curse Client and the download box appears for a second and nothing happens. I uninstalled Curse Client and all of the add ons such as Auctioneer etc and now nothing will reinstall at all, same problem where it pops up the download box and then nothing happens. Please help!!!

I'm running WinXP Pro with all Windows updates to date, and again it all worked before the 2.4 patch came out. It's not even connecting for updates or news or anything now! Not sure what else to do...

What browser are you using may I ask?

I got same problem, most addons broke after 2.4 in their own strange way, activating randomly or not appearing at all >.< I'm running Vista with IE and even the client is messing up, telling me to change settings for wow something

Yep I am getting the same problem, trying to download a quest helper but it says error. So i try one of the mirror downloads and it works. But now i dont know how to link it in WoW and activate it.
Can you advice?
Btw I am using IE as a browser.

Same goes here. Curse client doesn't do nothing, but mirror works. Quick question, why I use curse games if I don't get working update?

P.S. I'm using Mozilla Firefox.
