I’ll presume, given a DS920+, you’re using DSM 7.
Based on this, what you’re describing sounds like it got disassociated (unclaimed) from your account.
To resolve this:
- Uninstall the package with the KEEP (first radio button) option
- Install the same package again – HOWEVER –
- Select the “Install using Plex Claim Token” option
- Click the link which get’s a claim token
- COPY the given token into your browser and then paste back in the Installation window
- Click NEXT - NEXT - DONE and let it finish
- If successful, you’ll see it claimed again for your username.
- All will be well again
