Enhanser Questions!

Hi guys, I have a few questions regarding Enhanser! Can anyone help.Firstly having downloaded the application and installed it no matter what I do nothing seems to change in FS. I have an nvidia 8500GT latest Driver 169.25. I locate the MFS 2004 profile and change various sections. My aim is to rid my system shimmer. I have the "Profile can be activated manuall ticked"1. Why does nothing change?2. Does Enhanser overide Nvidia Conrol Panel or work alongside.3. Do I have to close down FS9 to see the changes or do they work automatically?4. Do I have Anti-Aliasing within FS ticked or not?Can anyone help? And what settings do you use??To fix the shimmers would be my best Xmas Present Ever! Is Santa out there??
