The online manual contains Installation instructions and a Quick Start guide.
This is a fully functional 30 day trial that can be converted into a full version by the purchase of a licence key. When operating in trial mode a small message is displayed below the web-part. Purchasing a licence key removes the time limit and trial message.
To upgrade to a later Minor version (e.g. 2.5 to 2.6) without losing any existing settings simply download and install the new trial version and select "Upgrade" - there is no need to remove the old version first. All your settings will be saved and transferred to the new version and your existing license key will automatically unlock the full version.
To upgrade a Major version (e.g. v2.4 to v3.0) you can also install the latest version 'over the top' but you will need new License Key - this is free of charge if you have an active Premium Support agreement, otherwise you will need to purchase a new license.
Please read the upgrade notes before installing.
