When I use WidescreenFix by ThirteenAG it makes doesn't let my open my game and windows states "speed.exe stopped working". For more information I am using the original game from when it came out for PC as CD-ROM version, so it is probably 1.0? I also tried with the patch 4, but it doesn't work.

Please update the game first with the patch supplied on the PCGW page, this should fix it.
I already did that, but I found the problem. My uniWS was interfering with my NFSU, removing it fixed my problem
