Runtime Error when trying to run the game after apply the patch for play online

[Predator1989]

Hello. I'm having a problem trying to apply this patch to play online:
I replaced the .exe and now, when I execute the game, automatically appears this message:
"Runtime Error!

Program: D:\Program Files (x86)\Unreal Tournament 3\Binaries\UT3.exe

This aplication has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information".

Has anyone any idea of what's happening and how to solve it? Thanks a lot.

OK, the problema was my game version was 2.0 (and 2.1 is needed, I thought Patch 5 was installed :S).
