# Troubleshooting

> Fixes for common workspace and playback issues.

Common issues and how to resolve them. If none of these help, reach out via
[Contact & Support](/en/help/support).

## Workspace

<AccordionGroup>
  <Accordion title="My code won't run / the terminal is unresponsive">
    The workspace relies on remote compilation. Check your network connection and
    reload the lesson. If it persists, try a different network or report it to
    support with the course and lesson name.
  </Accordion>

  <Accordion title="The live preview isn't updating">
    Make sure your code compiles without errors — a broken state can stop the
    preview from rendering. Use the [AI Tutor](/en/learn/ai-tutor) to find the
    issue, then reload the preview.
  </Accordion>

  <Accordion title="GitHub sync isn't working">
    Confirm GitHub is connected under **Settings → Security → Connected social
    accounts**. Reconnect if needed, then retry. See
    [GitHub Sync](/en/learn/workspace/github-sync).
  </Accordion>
</AccordionGroup>

## Account & access

<AccordionGroup>
  <Accordion title="I can't access a course">
    Check that your [membership](/en/platform/membership-tiers) covers that
    course's access type. Membership (MEMBER) courses require a paid membership
    (Basic and above).
  </Accordion>

  <Accordion title="My language didn't change">
    Set your default under **Settings → Profile → Language**, or use the language
    switcher. Some specific courses may not be translated yet — the English
    version remains available.
  </Accordion>

  <Accordion title="I'm out of AI Credits">
    Credits refresh monthly. For more, consider a higher
    [plan](/en/platform/membership-tiers) — higher tiers also raise your monthly
    **AI Import allowance** (Basic 5, Pro 10, Creator unlimited).
