certain website give 302 error

I have no idea what could have caused this problem to happen recently, but it's been bothering me so much that I've decided to come here for help. It appears from other messages I've read on here that they may have the same problem I'm having. It's really frustrating because it seems like I've tried everything to figure this out and nothing is working! I've cleared the cache, reset safari, even downloaded firefox and the funny thing is, firefox won't even open it. So then I thought, maybe it's a problem with my wireless network, even though I can't figure out why it would be. So I connected my computer directly to my cable modem connection and it still won't open these websites I would really like to open for me! I have tried to find a common bond with these websites, so far all I can figure is they are ones that have flash and/or are hosted by godaddy. I have the latest version of safari, but I don't know that it really matters if it won't open in firefox either!
