i had the same issues as Jose. After some hours of troubleshooting (together with Mr-Man) i found a solution for my enviroment. I found the an article, that descibe a clean uninstall of the saitek drivers and software. you can found the description here: http://simhq.com/forum/ubbthreads.php/topics/3802279/Saitek_driver_problem
And also i found a youtube video, that descibe the uninstallation.
After that, i reinstall the saitek drivers 7.0.53.6.
And it works. Great!
