PixelGenius Photokit Sharpener Activation

Has anyone successfully activated photokit sharpener (1.2.6) using Photoshop CS3 and Leopard? I complete the activation process and get a successful install message box, but when I try to use the plugin I get the message the software must be activated. I have redownloaded the plugin, am using the current esellerate program, deleted preferences, everything. I tried everything Pixelgenius support suggested, but no luck. TIA
