Please note: from version 11.0.0.0 the old 8-digit license key is no longer valid. It was replaced by a longer license key, which contains the company name, or first and last name, as well as the postal code and city of the licensee in encrypted form. This data is displayed in the popup menu under "Info PixelRuler...".
If you have problems with the new license key, please reply to your old email which contains the original PixelRuler license order, so I can identify you.
