### Summary

The DMX Previs Sample ([fab.com/listings/5ce617bc-b926-4db5-936b-a0733a5da72d](http://fab.com/listings/5ce617bc-b926-4db5-936b-a0733a5da72d)) currently returns “Sorry, we couldn’t find that page.” This happens both on [fab.com](http://fab.com) and when opening the sample from the Epic Games Launcher. The link in the official DMX Previs documentation (UE 5.7/5.8) leads to the same dead page.  
Is the sample temporarily unavailable, or has it moved to a new listing? I’d like to add it to my library for UE 5.7.

### Steps to Reproduce

1. Open the DMX Previs Sample documentation page (UE 5.7/5.8) and click the “DMX Previs sample” link under Getting Started.
2. Alternatively, open the Epic Games Launcher, go to Fab and click the DMX Previs Sample.
3. The page shows “Sorry, we couldn’t find that page.”

### Expected Result

The DMX Previs Sample listing opens and can be added to My Library for use with UE 5.7.

### Observed Result

Both the website and the launcher lead to a 404 “Page not found” page. The sample cannot be added to the library.
