# Fix “We couldn’t load your video preview” in the editor

> The editor couldn’t download or start its preview, usually because of a network hiccup or a tab left open across a Tella update. Click Try again or Reload; your video and edits are safe.

The editor shows **We couldn’t load your video preview** when its preview fails to download or start, and **Tella was updated while this tab was open** when the tab is running an older version of Tella. Click **Try again** or **Reload** on the screen. Your video and edits are safe.

## “Tella was updated while this tab was open”

Tella released an update after you opened this tab, and the tab can no longer download the parts of the editor it needs. Click **Reload** to open the latest version.

To avoid it, reload editor tabs you have left open for a long time (for example, overnight) before you start editing again.

## “We couldn’t load your video preview”

The editor downloads its preview engine when it opens. If that download is interrupted or the engine fails to start, you see this message.

1. Click **Try again**.
2. If it fails again, check your internet connection and reload the page.
3. Turn off VPNs, ad blockers, or privacy extensions for tella.tv, then reload. Some block the files the editor downloads.
4. On a work network, ask your IT team to allow `tella.tv` and its downloads; some company firewalls block large downloads from websites.
5. Close other tabs and apps if your computer is low on memory, then reload.

If the message still appears, check [status.tella.com](https://status.tella.com) in case Tella is having an outage.

## Still seeing it?

Ask the [support assistant](/docs/help/support/ai-assistant) to open a bug report, and include the browser you use and whether other videos open in the editor.
