Ive now got WindowBlinds 4.5 and recieved the Serial number for it but where do you type in the serial number?
A bit from WindowBlind's site...
Download the enhanced version of WindowBlinds from the link that is emailed to you. If you are running WindowBlinds, unload it (set the skin to Windows Classic) and then install. If you are prompted to reboot, do so. You should be asked for your serial code upon reloading WindowBlinds - once you enter it, registered functions (like skinned scrollbars) will become available.
