Hi Sue,
Clearly it thinks you're French... French aircraft had an inverted throttle, where you pulled back to increase engine speed. It's like their tanks!
You'll need to open your controls cfg file, which is either CFS3.xca or whatever_name_you_gave_it.xca, and you'll find this in your app data file here:
C:\Users\your user name\AppData\Roaming\Microsoft\Combat Flight Simulator 3.0
You'll need to ensure that hidden folders are visible first, or you won't be able to find it.
Open the xca file using Windows Notepad, which you might as well set as default.
Look for this line:
<Axis ID="Throttle" Action="AXIS_THROTTLE_SET" Scale="127" Nullzone="1"/>
And see what it says. I'd expect a negative sign has got in there somewhere...
My own looks like this overall:

Note that I don't use the twist-stick rudder, but my key attributions are not straight out of the box either!
If you can find what yours says and post it up, we can try and see what the matter is.
