My TIR3 also stopped working with FSX.
First some info about my setup...
* Asus A8N-E mainboard with N-Force4 Ultra chipset, Athlon 64 3200+, 2 GB of memory, Asus 6600GT Extreme with 128 MB RAM (or was it 256 MB? Whatever.)
* Windows XP Professional with SP2 installed
* FSX Standard edition with SP1 installed
* TIR3, no vector expansion
* NOD32 virus scanner
(All software is legal.)
My TIR3 works just fine with Falcon 4 Allied Force, the blue light comes on when I'm about to fly. But with FSX, the blue light does not come on.
I started 'playing' FSX about a week ago after I purchased both XP and FSX. It used to work great, until I think I installed FSX SP1. Around that time I also started tweaking graphics settings, it might have to do something with that. Somewhere on a forum these settings were recommended:

(scroll down to "For a more detailed list CLICK HERE", click the link and see the 6600GT-column, I used that setup)
After that I started having crashes when I switch to the cockpit view under F10. I could fly as much as I want, until I switched to F10. Well and after a couple of CTD's the blue light didn't come on again. So what caused these crashes? SP1? After a clean reinstall of FSX + SP1, without changing the settings, I can switch as much as I want between F9 and F10 so it doesn't look like it. Then I guess the tweaking caused it.
Anyway, after a clean install of FSX, the blue light didn't come on. Added SP1, still doesn't work. Uninstalled TrackIR, installed it again, still doesn't work. Plugged it into another USB-port (some of the driver parts get reinstalled then, right?), didn't help.
I read stuff about SimConnect and the SDK, but I have the standard version of FSX so the SDK is not available to me is it? At least I can not find it on the DVD's.
I do have these 2 directories you are talking about in the forums:
x86_Microsoft.FlightSimulator.SimConnect_67c7c14424d61b5b_10.0.60905.0_x-ww_429211e9
x86_Microsoft.FlightSimulator.SimConnect_67c7c14424d61b5b_10.0.61242.0_x-ww_35e8ee9a
But they both only contain 1 file: SimConnect.dll
Also tried disabling my virusscanner, didn't help. I was running Windows 2000 until a week ago, so you can imagine that my XP-setup is still quite clean. Therefore if you would like me to try reinstalling XP, that is no problem! But that's more like a workaround instead of a solution isn't it? Then we won't know what caused the problem.
Do you have anything else I could try?
Thanks in advance!
