Please contact sales (email@example.com) and ask for a trial extension key.
The License Manager tool can be used to activate the trial extension key and extend the trial expiration date.
License Manager is installed to Program Files (x86)\Common Files\GrapeCity\Components\GrapeCity.LicenseManager.exe, and a shortcut is added for it in the Start menu group GrapeCity.
The tool looks like this when you open it:

For you, it will say "Trial License (Expired)" for Spread.NET 6 instead of for Active Reports 7 -- click on the "Activate" link to activate the trial extension key.
Hope that helps, and thanks for your interest in Spread.NET! Please let us know if you have any questions or problems.
