Yes, I'm still experiencing it.
I actually found a workaround which is to disconnect from the Internet (eg turn off WiFi) before launching, and it will launch OK - though it errors that it failed to load the list of curated services (obviously due to no network to fetch it).
Any time I launch it while connected to the Internet it will hang on the "Initializing" screen until I turn WiFi off, then it continues onward, and shows the IDE.
Let me know if there's any way I can help troubleshoot this further?
Hmm, I've tried it from two different ISPs, and neither of them are proxying the traffic. What's the host/port it's trying to connect to, so I can make sure I'm able to connect?
Steve, I think this is the wrong URL feed I'm giving you, now that I reread your post, but it is one of the feeds that the XDK will attempt to read from. This one has a backup built into the XDK, so it's not so noticeable if it fails, but the one that I believe your message refers to should be coming from a similar location.
