probs with Universal widescreen patcher to nfs underground 1

[Mikki1992]

Have a little problem in getting universal widescreen patcher to work on nfs underground, I must have resolution up to 1680x945.

I have:
1: set the resolution in game to 640x480
2: found throughout the game Universal widescreen and set the resolution to 1680x945 and pulled patch button but it does not help the game is still running at a maximum of 1024x768.

Someone who can see what I'm doing wrong or what I need to do that it works.

I am from Denmark, so excuse my bad English.
