The Store Commander version your are trying to use is too recent for your current support pack. Please use an older version or renew your support on https://www.storecommander.com to use the latest updates.
This means that your support and update period has expired and therefore updates cannot be applied.
You can log onto your account www.storecommander.com > My licenses to add 6/12 months period to be able to apply Store Commander updates and access our dedicated support (Solo & Multistore licenses).
