Can software upgrade be undone?

I've upgraded my AB to version 6.30 after which I was told my entitlement for free upgrade had expired.
What should I do to correct my mistake? Do I need to reinstall an older version of AB?

You can easily downgrade to the previous version. Just close AmiBroker and run the previous version's installer. The whole operation should take no longer than a minute ...

Or renew your licence and take advantage of the latest version(s) :slight_smile:
