Deana,
I have cleared your Activation count. What you should now do is uninstall WB, then reboot your PC. Then open the System Registry (Start-> Run -> type regedit, hit Enter) Look for , and delete any of the following Keys, if found;
HKEY_CURRENT_USER\Software\Stardock\WindowBlinds
HKEY_LOCAL_MACHINE\SOFTWARE\Stardock\WindowBlinds
HKEY_LOCAL_MACHINE\SOFTWARE\Stardock\ObjectDesktop\WindowBlinds
Then, use Impulse to re-install WB, it shouldn't ask you to Activate it.
