CH Yoke vs XP don't like each other????

HI there,I have just upgraded to XP and I am satisfied with the performance of FS2002.The problem is: I can't get the Yoke/Rudder to work.I already did a search on the forums and lots of people have similar problems to mine and I tried everything including installing the control manager etc.Now, what happens is very strange. Some of the buttons do not work and some of them activate 2 different functions. For example, if I press button 12, button 10 is also activated. This happens with other buttons as well. On the other hand the hat switch does not work, only up and down works!What is even more strange is that sometimes everything works fine!The rest of the problems like rudders stop working after a few minutes etc happen here as well!Any clues or solutions please!!!
