First of all , I'm sorry for posting here. And I have a problem with Windows 7 Loader. I use it and It says the certificate is installed then It restarts and It says 30 days left. I've tried using WATFIX, Doesn't work, I've tried using Active @ Killdisk to format and destroy any protection and It's still not working, My laptop is Dell inspirion N5720 with Windows Home Premium 64 without SP1. Thank you for your support.
