Looks like you know it’s temporarily not working, but only to make sure…
The window pops up empty with a message.
The error you’re seeing is:
ERROR_FILE_NOT_FOUND (0x2)
“The system cannot find the file specified.”
According to the documentation …
“In offline mode, HttpSendRequest returns ERROR_FILE_NOT_FOUND if the resource is not found in the Internet cache.”
This is likely happening because you have Internet Explorer set to “offline mode” and we happen to use the same settings for our http requests as IE. I will add some code to override this behavior. But, in the meantime, you should be able to work around this issue by making sure IE is offline mode is disabled. Try following the steps outlined here… http://support.microsoft.com/kb/923737
Hi,
Thanks for the reply. I’m trying the procedures in the microsoft’s support page, but only as a note, I’m using chrome as my web browser. Does it make any difference for the samples page loading or not, or do you mean Rocket’s http requests settings are always taken from IE?
The samples windows is working now.
Thanks.
Hi Athos,
We recently changed where this UI downloads text/files from due to the following post:
https://rocket.unrealengine.com/questions/4713/is-anyone-else-having-trouble-downloading-the-demo.html
After changing, we were able to load up the UI fine. But you might need to reload Rocket (and make sure you’re connected to the internet) for the changes to propogate.
The Samples window is still not working here. Only worked a single time when I opened up the editor. 
Am I missing something here?
Thanks in advance,
Can you try creating a new project and then opening the Samples window? The Samples window caches it’s files local to the project, so opening a new project will force the window to re-download its contents.
Also make sure you have a working internet connection.
Let me know if you see a difference.
I created a new project now, but it’s still not working.
First time I’ve opened Rocket Editor windows opened a pop-up telling me Rocket Editor was asking permission to connect etc. I’ve chosen the type of internet connection to “private networks, like office networks etc” (for being safer). Can this be the reason? Would it make any difference if I have chosen “public networks” (I guess not)?
Samples window worked yesterday here, but today, with the same project opened, stopped working again.
If the problem is still that content doesn’t show up in the UI (and not that the Samples don’t download successfully), we would need logs to investigate further. This can be found either via the “output log” window, or in the “Saved” folder in your project directory.
In the meantime, I’ll send you an email with a direct download link to get you going.
The output from the Output Log Window, the lines after opening the Samples window and clicking ‘try again’:
