CH yoke and pedals draw power through the USB line and can cause extra heat in the power supply. I have eliminated CTDs on three computers by transferring USB flight controls to an external USB hub with its own power source.

Hi Bill,If you moved the folder containing the AFCADs to another place (or even just the contents) the UT ones are prefixed with F1UT_.Otherwise there is an UT Automatic Updater available via Start..Programs..UT..UT Updater. This gives you the option of checking for updates which should scan your system and find missing ones. In your case... quite a lot :-)Cheers,
