Hi, the same happened here, but after hours of searching found that disabling NVidia FirstPacket everything works great, hope that this works, if not:

Possible Fix 1: nVidia nForce driver components

I have an EVGA i650 Ultra motherboard in my system with the nForce drivers installed. Either of the two following nForce driver components / features might cause this problem in Vista.

   1. nVidia MediaShield
   2. nVidia - ForceWare Network Access Manager

Uninstall them to see if it clears up the issue. I uninstalled both of them and it was fixed, so it could be either.

Possible Cause 2: Vista's DEP Protection

To fix this issue, you might need to disable DEP in Vista. To disable DEP, perform the following (found these steps HERE.)

1. Click Start
2. Click All Programs
3. Click Accessories
4. Right Click on Command Prompt
5. Left click on Run as Administrator
6. Click the Allow button if it asks you for permission
7. Type or copy and paste this into the command prompt window:

bcdedit.exe /set {current} nx AlwaysOff

8. You should see the message "Operation Completed Successfully"
9. Reboot and DEP should be off.

Possible Cause 3: Administrator Mode

You may also want to try running the application as an administrator. You can do this by right clicking on the short-cut, selecting properties and checking the "Run as administrator" box.
