Hi bigmuscle, I have a small problem : I had to reinstall Windows 8 Pro on my PC. When i reinstalled Aero Glass, it gave me the "please donate" pop-up again. So i had to recreate a license key from the website, but now i won't be able to create a third key for my laptop. Is it possible to delete the first one and only keep the last two ? I can PM you my PayPal address and Zip Code. Thank you in advance, and keep up the good work !
