Whenever I go to the JK3 website of Filefront it just comes up with the regular Filefront.com for some reason.It's really annoying.
http://jediknight2.filefront.com/ Works fine for me.
Pro-Filer's been adding new network sites, so chances are, the redirect domains are down temporarily. Sub-domains should be working just fine.
Try reporting the error in the FileFront Helpdesk forum, you'll likely get a better response from FileFront staff there.
I don't know how, and I don't know why, but this is totally Sheep's fault.
