I'll try it again tonight when I'm back on home WiFi and will report the results. It sounds like that may be it, since the next day I loaded it up on my work machine, complete with proxy config, and everything worked fine...
We are in the process of resolving this issue - it turns out to be a server infrastructure issue on a few of our provisioned nodes. We will ping this thread once again when the issue is fully resolved. Thanks.
Apologies, this issue is not (seemingly?) directly related to the problem we've been experiencing on our servers - I read the thread too fast. But, do try again later tonight just in case our solution to one problem happens to resolve your problem as well. Thanks.
Your issue is directly related to our server problems I mentioned two posts up (http://www.sencha.com/forum/showthre...l=1#post726061). This can be "worked around" by closing your application and retrying over and over again, and "one time" it should work. However, you can wait until later today when we have the issue resolved; I will ping this thread at that time.
