I installed Windows 7 and used daz loader to activate, every thing went perfect. Now a couple weeks on and I discovered it is no longer activated, I am unsure what caused it. I have done a few things to my PC, I started using MSE for virus protection. I deleted xp from dual booting. I made a new partition and installed Fedora. I have tried reactivating with daz loader again, but it says "unable to achieve required system access. I also tried Hazar loader and My Digital Activator, but these run and will change OEm branding etc, but fail to activate Windows 7 and remains in trial period. I have 19 days left and would much appreciate any advice.
