I get the spinning rings. So I did what you said for Internet explorer script enable and blah blah blah. I enabled it and check if it was offline and it wasn't. It still doesn't work.
So I tried the DNS arcticle soulution. No help at all.
Then everything else.
I also downloaded the standalone client. That doesn't even work.
Can't you guys make a launcher for firefox, or any other browser. I bought LoL at the store and I'm really getting sick of following steps that don't even work, and I might take it back because I've been up since 8 last night trying to figure this out.
