Hi,
Please update to the current version first. Your license does cover the current version. However after you update to the current version, make sure you go to your license key page to download a license key for the current version (v2023) and use the new key instead.
If the problem still occurs after you update to the current version, please try to enable EO Worker process:

Thanks!
