I was planning on visiting the new uproar space to check it out and I was stuck in a faded home loading screen with with the WWW spinning for almost an hour. I had to reset Home. I tried clearing my cache, and Deleting Home and reinstalling to see if I could fix this. But no luck. So I don't think its my system because all the other spaces load corectly.
Are you using a wifi connection?
You also might want to know Uproar works horribly on wifi. I kept getting frozen in the space, getting booted with errors in game, and the game never loading up while in the space. Once I switched it to a wired connection it works just great.
Uproar is still having an issue with loading in the Arena. Infact, the game activation icon isn't even showing up. And I'm not the only one experiencing this. Others in the Arena are still waiting.
My stet-up is wired. I have cleared my Cache. I've left and come back.
I am able to launch from the Action District. But I do like variety.
A side note: Just now while playing the game in the Action District, there was a sudden hic-cup where I was suddenly out of the game, but still holding my rifle. The others I had been playing with were still in the game while I was out. What I saw before me was Uproar and the Action District over-lapping. People from the game continued playing without seeing the people in the Action District - with the Action District people unaware of the game. And I could still climb the Uproar set... It was pretty interesting.
Update: After a few days, and a few tries, the game activation icon has shown up in the Arena. But that doesn't mean that there isn't an issue...
I have the exact same issues as you, Conrad, even with the sudden boot from the game. My connection is wireless, though.
