Well I just tried my demo account it logged in right aways. I selected the demo server and when I went to log back into my live account, it had server1 selected instead of the demo server. My live account has server2 selected. You might want to try creating a demo account from the PC platform and then entering the log in details in the mobile platform. Here's the direct d/l for the PC platform.
