Daniel, What devices are you trying to use. There are some Saitek that FSUIPC will not connect with, such as the "Multi panel".
The Throttle Quad, yoke and pedals do well. Make sure they are still recognized by your computer in the devices page of your control panel.
I have the multi panel, which FSUIPC will not recognize and use a freeware "spad" download to operate it, and now I very seldom use it as it does not work well with any of my payware A/C. It is taking up space. I have got rid of the Saitek Yoke, throttles and pedals and use another company, not CH either.
Checkout this forum on AVSIM;

The Yoke and Foot pedals work well in FSUIPC, but you will get conflicting assignments that need to be removed from the FS assignements, or use the FS assignements. But you cannot use both.
I am sure you tried reloading the FSUIPC and restart your computer. Are you using the free version of FSUIPC or the paid copy?
Good Luck
