Another thing you can do is:
Debug the app. Check to see the architecture
is raising any exceptions (you can see this in the output window in flex
builder). I have had the same type of thing happen to me. It isbecause when
flex raises and exception, it may stop the processing of the app (Or the
current frame which is basically the loader). The architecture will raise and
exception if you add a view helper with the same name, or you call a view
helper that doesn’t exist (Like a view helper that is in a child of a
viewstack that has not been initialized yet.)

Cairngorm namspace bug
Do you have a directory in your webapp
com/visualio/play/view/ containing
DemoViewHelper.as and
LoginViewHelper.as (you seem to be trying to
instantiate
both classes)
<playView:DemoViewHelper> is going to look
for
com/visualio/play/view/DemoViewHelper.as
while
<playView:LoginViewHelper> in your
Login.mxml file is going
to try and locate
com/visualio/play/view/LoginViewHelper.as
check both those files are there.
