Curseforge.com seems to be down - I keep getting 500 Internal Server Srror.

I'm getting the same issue on a lot of other Curse items, I'm trying to re-download the Curse Client, and I keep getting the Internal Server Error. :( and when I try to manually download the add-ons I need, it says link expired. Help?

Unfortunately, you can't fix it. It's a problem on their end. You have to wait for them to fix it.

curseforge.com and wowace.com are taken down once a week or so for updates and maintenance.
