I cannot update Tweaking.com v3.9.0.4. I have tried with v0.5, 0.6 and now 0.7. I have the Pro version. I am on Windows 7 Home Premium. I have tried uninstalling/reinstalling, turning off Norton, in safe mode (which worked temporarily until my PC went back to normal mode), even using Tweaking.com to repair but nothing has worked. The error message I receive after updating which I am told is "successful" and then opening Tweaking.com is "Error at hooking API 'NtProtectVirtualMemory' Dumping first 32 bytes. Please see screenshot with the rest of the numbers it gives me. Version 3.9.0.4 works perfectly okay so sticking with this for now without updating. Thanks.
