After a new update from Boot Camp on windows 7 my functionkey doesn't work anymore!!

Hello guys,

I never used this Community but now I've a problem and I can't solve it by myself so I hope you guys would like to help me.

Specifications:

Macbook Pro (mid 2010)

13,3''

With Boot Camp on it (Windows 7 Ultimate)

Problem:

Today (26-12-2012) there came a message that there was a new update for Boot Camp (something with Boot Camp 3.3 I saw). I installed the new update but when my Macbook restrated I tried if my functionkeys (like volume and brightness) correctly worked but indeed they didn't worked after the update.

I restarted my Macbook like 10 times but it still doesn't work 😟

I hope you guys have a solution for me so the functionkeys will work correctly.
