Hi everyone I am now to this forum, My fs2004 works fine, and my fsuipc as well but when i click on the buttons + switches tab or axis assignment tab it freezes and fs2004 freezes as well, i can only close it with task manager. It will only response if i click or move something with the saitek yoke and then i will freeze again when prompt if i want to use fs control or key board. So it will also freeze if i have nothing connecting to the computer. Please help because i want to bind my saitek button as a fuel cutoff switch. Greetings
