I seem to be having the exact same problem that tamaroa was having. I cannot download any Rival casinos & I can download RTGs, but I cannot download any games or (only in some) go to the cashier.I have NOOO idea what the problem is. The only thing I think it could possibly be is my modem b'cuz I tried downloading the apps on my friends computer with my modem & the same thing happened.Tamaroa..... I am also using Windows XP SP3, but I don't think the problem is with my systm. Are you using a wireless modem? I have cricket broadband & I have noticed that I cannot successfully launch the data connect, but I am still able to get on the internet. Weird. Maybe this has something to do with it.If any1 has any suggestions, I would greatly appreciate any input.
